Greetings and welcome to the board
Sorry to report that I do not know of any private hub on this board. You prolly picked up on a thread about someone suggesting the thing but if it were the case, it never flew.
From what i've read, it would need someone with a server willing to do the deed and take the time. So far, it hasen't been the case. But hey, stick around, it's a very nice virtual living room
PS : been several hundred hours on soulseek, the donkey and other apps, never had any problems
