My league section of the forums is on permanent collapsed mode for a couple of days now,i cant acces from the main page,but i can go to the leagues section via "new posts"......sup there?.
Official RD leagues have been that way for some time. It makes sense to do this with the supported leagues too. It was done to tidy the forum up. The main forum page was ridiculously long, it makes sense to integrate them within the games they belong to.
You can access them by going to the relevant game sub-forum (e.g rFactor, RACE 07, iRacing, Game Stock Car etc)
