I hate to be that person, but - they didn't go anywhere. Fact is, the vast majority of rpers A) get excited and then lose interest in a matter of days when things go more slowly than they wanted, B) only had a character idea and once it's down on paper, they lose the desire to rp, C) contact a bunch of different people only to realize they've picked up way too many rps and something has to go, or D) it was just a craving and it passed. These people can still get dedicated to a particular rp, just that for a lot of other rps, they can't do it. I've only met a small handful of people who remained dedicated to their rps despite any or all of the above occurring.

[s]You're probably just bitter right now, but I can't blame you. I'm feeling a bit bitter myself because my most recent interest check took off, only for everyone to vanish EXCEPT the guy who didn't know if he could do it. It's disappointing, and all I can suggest is trying again maybe in a few weeks if the three aren't enough.[/s]
