If I have a good idea, I try to write it down. Doesn't have to go into the post right away, doesn't have to be flushed out. Sometimes a good idea, when written down, doesn't look that good anymore too.

I try to post at least once a week. I think that's best for an RP's suitability. Yea, in the beginning you can get hundreds of ideas and post daily if you'd like, but not everyone can make the RP thing life. If you find yourself willing to write more, but are put off by slow responses, maybe join another RP and keep up with both of them?
