You don't have to ask to friend or defriend my journal, or to link to anything I post, or to crit my stuff, or to make sequels/podfics/fanart/whatever based on it, etc. As long as credit is given, you don't need my permission.
I WOULD especially love it if you post your work on the Archive of Our Own (http://ao3.org) and cite my original story as a related work there, because then I can easily link back to you from the original story. :D
If you make a translation/remix/etc of one of my things and don't have an AO3 account, I have invites, just PM me your email address for one, and if it's for one of my stories that isn't on the AO3 yet, let me know and I'll put it up so you can link it.
PS: anon commenting is disabled here on my livejournal because I was getting badly spammed. You can comment anon on my Dreamwidth journal instead if you want.
