I have added Usergroups to this Forum, becoming a member of a usergroup will unlock certain forums for you. For instance, if you join the "Animaniacs" usergroup, you will get to see the Anime Discussion board.
Select "Groups" from the Menu for a list of your current group membership and the ones that you can join.
You will likely find that you already belong to a group. Anyone who has submitted original content to the AC is in the Writer group, this unlocks Idea Exchange and Talent Ads. Fanfiction-only writers and regular members will not have access to these forums. You will also find that you are in a group for the Genre that your original story is in. This currently serves no purpose but will allow benefits in the future.
That is all, let me know if you find any bugs!
