The place on GameFAQs Message Boards where users talk about Mega Man, but not really. Cait Sith Fortune lives there, and he's a pretty cool guy. So does Sub Tank, Lumino, Paromin, and even more. Sometimes we even get special guests and they leave because they don't like it.

Once in a while we go on adventures and then we get banned. It's kinda dumb but hey, that's what Alt Account are for.
The MMSB is cool because I like apples.

I bet the MMSB is a social board about Mega Man
