You DO realize it's a 1x1, right? I have no real GMing to do, and waiting for people to post ('people' meaning 'you and only you') is hardly a chore. That's the beauty of 1x1's. We each wait for only ONE OTHER PERSON and therefore I have absolutely no complicated streams of activity flow that I constantly have to go through the trouble of un-clogging.
In other words, take as long as you need. It's noooo hassle to me, and since you're not holding up an entire team of people who could be going faster without you, there's no real reason to feel obligated to drop out.
1x1 RP's, man. Totally different beast from group RP's. Just post when you can post. *shrugs*
