Wouldn't comply with the eula, and it was removed due to bugs as Severe said, but if you had the same things it had last time, I.e a board with all the games on, it would have to be pretty big.. Because that was basically the only advantage it had over the other lobby if I remember correctly, it had a load of signs with all the games on, (also lots of the time it had no people in so you could spam out of boredom on minechat with nobody knowing, I mean, what, I never did that..) but anyway, I don't really think a new donor lobby is necessary. The amount of memories I have of the old one.. It would never be the same.
In other words, that's a long and useless paragraph because I wanted to think of reasons other than the eula but failed dramatically.
