Thanks for the feedback everyone...We're aware of the "Invalid Forum" issue and trying to fix it...It appears to be happening to some Members and not others making it very difficult to reproduce and resolve. Based on what I've gathered from some of you via PM and email, only the Protege-based Forums are coming up "Invalid" for some Members. Why some Members and not others is still a mystery.
I don't know if the forum titles themselves have anything to do with the problem...I noticed that all the Protege-based Forums had an accented "" which I have now replaced with a standard "e"...It's a stretch but it may have something to do with this problem...Please let me know, thanks for everyone's patience and cooperation!
