Just to clarify so we don't hopefully have a thread that keeps chasing it's tail...
1) We are having a staff merger, not a full site merger. Furocity admins are joining us on FA.
2) We are not merging databases, so there is no need to worry about user account name collisions.
3) Being banned on Furocity will not autoban you on FA, and vice versa.
4) FA has no plans to ban human, human+antho, or anthro+feral artwork or pornography.
5) Adult and Mature artwork involving 'cubs' in underage situations will remain banned from FA.
6) Furocity is a smaller furry art community that has much of the features people have been asking for on FA. ...and we're getting their coder team.
As for AUP changes, the rest of the admin staff have been working on several AUP revisions for quite some time, to allow for clarification of pre-existing rules and to close some wording loopholes, and has nothing to do with Furaffinity and Furocity merging. I hope to see some of these out by the end of next week, but that's Next Week, Valve Time (see http://en.wikipedia.org/wiki/Hofstadter%27s_law )
