It's pretty difficult to keep people motivated on forums these days, I think. I run a forum in a similar situation... activity peaks then it just plummets. My activity died off on this site because I just don't make good music, so there's not a whole lot for me to contribute

I think the community here is really good, as we share similar interests / music styles, and everybody has awesome personalities, but you can't really get people to be active, since it has to come naturally. As long as there's some way to keep in contact, it won't matter what happens, really. If there's ever a point where I have to ask myself, "whatever happened to HighVoltage, StudioStar, Mo?" Then we've failed as internet people.
Just like the old BKR.. it was a good run. Shame it sort of ends up a similar fate.
