My problem is similar to Captain's, but reversed. I currently have thirteen active roleplays - fourteen, meaning I have yet to give a response, but it will happen soon (after finals, promise!), or somebody else has yet to give me a response, but they've informed me why they are taking so long, so I know it's still being continued.
However, I also have six more roleplays that are stalled, or the members haven't logged on in weeks, so.. they're on hold. *shrugs*
When I get busy like I have this quarter, I get frantic about replying, but due to the nature of my posting style (long and detailed, posting every 1-3 days), sometimes I'm flooded with replies, and sometimes I'm too free. ^^; Oh well. At the moment, I feel satisfied, especially since there are a few that I am really enjoying, and one in the works that I am looking forward to, very much.
