hm, at this point, it's not really going to be a "move", but a "fork". It means the wikia is going to be copied onto another place and continued in itself by a group of people.
It is currently unknown how many will focus on the new wiki. Notice the term focus. I still will not use "move" because you can contribute on both. You're not locked onto contributing to one wiki, you can freely choose to edit any or both.
If you want to get an idea on the current feedback from the people in the subject of contributing to the new wikia, you can refer to this thread: link
yep, there are lots of players who do it on their profile page, check it out on frontpage activity feed at the bottom, there's a "Teitokus" tab. You can even copy their code, but ask on their walls first :)
