I don't know how many people were interested in Wakfu, or who play it. But there has recently been a guild formed who inhabit one of the islands (there are 5 in total), they have created a website, it is currently just a forum but a site is in the making, you can apply to be in the guild via their forum for help with the game, groups and such.
