I'm down to help 'ya out if you want. I'm not on tumblr as much as I used to be and I don't know absolutely everything about chahta but *shrug there's quite a few of us chahta okla here on tumblr... mostly it seems from choctaw nation (oklahoma) but I think there's a few folks from the MS band as well. Since my family is from choctaw nation (Smiths on my mom side... long story but idk who my father is but according to my mother, he is chahta too but idk his name or family's name) so most of these resources lean that way.
http://www.choctawschool.com - choctaw school is awesome because it has resources for both learning that chahta anumpa (choctaw language) and history and culture. the "iti fabvssa" link on the left side bar has articles about the culture and the "history" link on the left has a bunch of articles on the history. The "lessons" "vocabulary" and "lesson of the day" links on the top are great for internet resources on the language. Through that site, online language and culture classes are also available. I've known people who have taken them and they've told me that they're wonderful. You can also sign up for the Choctaw word of the day and the tribe will send you a chahta word lesson each day into your email along with the audio so that you can hear what the language is supposed to sound like. I would also recommend watching the video on the front page of the website called Choctaw Vowels with Betty Ward... that's been the most helpful to me of any lesson i"ve seen on there. After watching that video, I was able to read chahta and hear it in my head the way it's supposed to sound i'd say 85% of the time. Super helpful!
http://www.choctawnationculture.com/default.aspx - tells a bit more about choctaw culture & resources that Choctaw Nation provide.
https://www.youtube.com/channel/UC-ZKzkDatyp6JmmNPi5JXHA - Choctaw Nation of Oklahoma's youtube channel... idk it's kinda cool seeing short videos about what's going on with them historically and today
https://www.youtube.com/watch?v=j6w3mHVD8dk&list=PLtOyHfA4PHVFZ7vKAiisu8EQGnJ1tE3Go&index=1 - youtube playlist of an album that was put together of Choctaw and Chickasaw social dance songs. its cool to listen to and get to know what some of the traditional songs are.
Traditionally, one aspect of the choctaw spirituality were stomp dances and green corn ceremonies... from what I've heard Choctaw Nation is primarily a christian nation now and came out and said so much in the mid-1980s when Chief Hollis Roberts was trying to get Choctaw gaming/casinos to be a thing that the tribe invested in (many people at the time were against it because they considered it a sin)... but there are people here and there within the Choctaw Nation and Choctaw Band of Mississippi Indians that do still hold to the traditional spiritual ways (particularly in MS). Some folks just go to the Creek, Seminole, or Cherokee stomp dances to practice that way instead since, like I said, not many people practice the old spiritual ways in Choctaw Nation. Both the Choctaw Nation and the Creek Nation have particular days that they go to the Museum of the American Indian and display their culture and history.... on one of those days for the Creek Nation they did a demonstration of a stomp dance:https://www.youtube.com/watch?v=kwX98loS0h4
Choctaw Days 2013 @ Smithsonian: https://www.youtube.com/watch?v=pSpv6EP6zY4&list=PLS6nSmuURFJBzn847Kmn8vvD0zP36b68r - kinda cool, a lot of videos about dances, songs, crafts, food, prayers, etc there's also videos floating around youtube from Choctaw Days 2012 that feature other things like a choctaw traditional wedding demonstration (https://www.youtube.com/watch?v=z4rsmTc98Dg) just kinda gotta hunt them down since they're not all in one place that I can find now
https://www.youtube.com/playlist?list=PL024870B27F524BA5&feature=mh_lolz -some more youtube videos on choctaw culture and language and what not... disregard the first video, it's inaccurate as far as the language goes with the colors.
https://www.youtube.com/watch?v=jKm8oGwjMZw&list=PL69EE5FBB958540BD&index=7 - Yannash Scott is a Choctaw language speaker and teacher and teaches chahta anumpa at one of the local colleges in Choctaw nation. He made these videos teaching some of the choctaw language. They're pretty helpful.
https://www.facebook.com/groups/choctawnatives/ - Choctaw Natives is one of many chahta groups on Facebook, but this one is generally pretty open and friendly. Good place to talk to there chahta... particularly if you are just reconnecting.
ChoctawNation.com - is also super helpful. They have links for services to tribal members and those seeking to get enrolled (there's no blood quantum requirement for getting enrolled so you just need to track down your family tree to the person you believe to be on the dawes rolls and then get birth and death certificates for each person going back to that original enrollee and get your CDIB card [certificate of indian blood card] and contact the enrollment office who's info is on that site... I'll put a link to the Five "Civilized" Tribe's dawes rolls below). They also have news about what's going on with the tribe right now (like a MAJOR expansion to the Durant Choctaw Casino & Resort) and history and culture things.
http://www.choctawnation.com/news-room/biskinik-newspaper-archive/ - there's a link to the Biskinik Newspaper which is the tribal newspaper that is sent out to all enrolled citizens... but if you're unenrolled, like myself, you can also access it through that link. It's updated monthly.
https://www.facebook.com/choctawnationofoklahoma - Choctaw Nation FB Page good to use to look at the photos of events the tribe has had and also news... they'll give you a heads up for events like Choctaw Days (2014), Trail of Tears reenactment Walk, Labor Day Festival, Sign up/enrollment times for the Choctaw language and culture classes, etc.
