If you are referring to the "Recent Wiki Activity" on the right, then I think we shouldn't. Although we do have Wiki Activity page, I think it can be useful if you are not on the wiki activity page. It also only shows edits on pages so you dont have to be distracted by blogs and comments.
Hey again :) I was wondering if you know of anyway we could make a logo for our wiki, I'm certainly no graphic designer. If you can make a better one than i'm going to put up in a few minutes, then be my guest :3
I think I can make one for you, I will make it right after I leave this message. Do you want me to email you the logo or just uploud it on the wiki? I will try and make it as good as possible, but no promises. :)
