So one of the biggest Winx Club Forums, Magix Club, is going for a revival. It has like basically everything there is to do with Winx; RPs, fanfics, episode links, discussions, all the latest info, etc. Its been going a bit slow as of lately, but some of the members are taking initiative in an attempt to make the site more active again. So if you haven't already, make an account and take a look around! New members are always welcome and most people there are really friendly, plus its like one of the tops in terms of English Winx forums.
