I've never really understood the idea that someone would want to get a whole story written before posting... <g> At least not anything very long...
I didn't start posting Hearts Divided until I'd gotten the first third or so written, but then I couldn't resist the craving for feedback any longer <g> So, naturally, I ran out of buffer very quickly and started writing from week to week. Which is actually a pretty good way for me to work, because I have difficulty starting to write. Once I get started, I'm fine, it's just getting started (each and every time) that's a challenge. When I knew people were waiting for the next part in a few days... well, it was very motivating.
Um, anyway... once or twice a week is a decent posting schedule. Sooner or later it all turns into "as soon as I get it written!" anyway
