Hi, I know that you aren't talking to me, but let me answer your questions.
Q: when was this wiki founded? It seems there's a lot of mixed dates for joining, I'm a bit confused.
A: The wiki just founded around may this year, and regarding the confusion, we kinda import things from other wiki, thus their contribution are also recorded in this wiki.
Q: Also, can I help out with the wikia too? :D
A: To be honest, this wiki was meant to be hidden until it is representable. But if you want to help around, I can't stop you. Though I will keep track of the wiki activity and review each of them, so do expect some input from me if you decided to help :p
And I want to ask about something since I'm a bit interested about it: like I said above, this wiki was meant to be hidden for now; how did you find it?
Ah I see, that explain it. Thank you for answering. If you need help, you can go to community > contact admin and ask on their message board. I know the wiki still need a lot of work to get done, so help would be appreciated. And if you see some strict regulation or the kind, don't get me wrong. I am only trying to get http://www.swordartonline.wikia.com quality level since that's where I'm inspired to help on this wiki.
Well, the reason this wiki is hidden for now is because there are actually a wiki for accel world already existed (http://www.accelworld.wikia.com), but most (if not all) active editors refuses to contribute as long as Robyn (http://accelworld.wikia.com/wiki/Message_Wall:Robyn_Grayson) is still a bureaucrat there. We already went through heated discussion, heated poll to drag her down, and contact a FANDOM staff about this matter, but none worked. I know this barely give you any detail of the story, so if you want to know the detail, call me from my message board (this keep notifying mtt, that's why). So, the reason this Wikia is kept hidden is because we don't want her to disturb us or get involved here in any way. That's why we want to us become representable first to make it harder to attack us.
And you are free the make the anime mainpage, but for each episode we already have http://bb2039.wikia.com/wiki/Acceleration and so on. But we lack of redirects like episode 1 and so on because the original wiki remove them (damn Robyn) and I keep delaying it because I have too much work to do.
