how did you publish cleaved anonymously? like what did you do when you went to publish? and how did you claim it back later?
So either you use this link and generate a new fic posted straight to the collection, or you do it when you're creating the work from your homepage. Just go through the standard create new work flow, and then, when you reach the associations section, and the collections tab, type in anonymous (any of them work fine, I used the regular anon), then select the option. That should add the anon tag to the fic, so when you post, the fic will automaticlly be posted in the anonymous collection. This means it will not show your username or link to you in any way for readers. However, you will still be able to see it under your username, and in your fic collection when you're logged in.
But dw, no one else can (you can just log out of your profile and test it for yourself)
When you want to claim the fic, just remove the anon tag (same as when you're removing a tumblr tag, just click x) and the fic will start showing your username.
