Also there is another wiki I want to join. Im kinda a new comer to wikia and dont realy understand how I joined this one. There is another one but I don't know how to join it. Could you tell me? You can check it out, it's twilightsaga.wikia
You should be able to edit your icon (If you mean this) on your user profile. If it doesn't work, try it in another browser. And if you mean the picture you added to your page, you have to click "edit" and then simply remove it and put a new one onto the page.
You join a wiki once you make your first edit. This means your account will automatically be a part of the wiki when you start/edit a page, or write a comment/blog post on a wiki.
That is currently unknown, because Tribble stated she will work on it alone instead of introducing her new animator team, and she is busy with college life. Maybe we will hear more about it when the holidays start.
