RPing is generally grabbing two or three RPs depending on what you can handle and then seeing which ones last. I'm in one group RP that's just passed it's 3rd year anniversary, and it's gained and lost a bunch of people over the years. Probably a third of the original cast is gone. I'm also in a 1x1 RP that's been going for 11 months which is pretty solid, but during those 11 months I've had like 3 or 4 other 1x1s drop for various reasons.

It happens. Stuff gets in the way and inspiration comes and goes.
