Hey! This actually isn't a fic related question, but a layout question. How did you figure out how to make the tag list? I mean, how were you able to create a linked page with all of those different links? Links within links are too much for me to figure out on my own!
Okay, well, originally my Tags List was just an alphabetised list of all 570 tags that I had at the time (there's been more since then, I'm pretty sure we're almost at 600) – and then people were saying that it's hard to find a tag in there because everything was all grouped together?
So someone very kindly pointed me in the direction of destielfanfic, who has a brilliantly organised Tags list, and I had a poke around to see where they got their HTML for their tags list (I've quite forgotten the blog they've got it from, but I can have another look around for you).
As for creating a page full of links – I spent three nights typing up every single URL for the tags (with help of copy/paste for the more repetitive parts) and checking spelling to make sure they work.
In the Tumblr layout design, you just have to create as many new pages as you need and then just link them to each other to create several different pages.
