Lot of very friendly and interesting people there, some of the coolest bronies I’ve meet in the fandom make their home their. When it comes back online (and the admin is in the process of transferring the data to a new host), I highly recommend giving it a try if you are into that sort of stuff.
I have word from a reliable source that the forums will be back up soon, but ALL content was lost. Everybody will have to re-register their accounts as well.
