With the players joining our advanced RP, we care about what they write and what they achieve with it, not how long they write. Sometimes, a post can be nigh-essay length, other times it can just be the two-three decent paragraphs. We don't even worry about how much of the setting lore they know before joining, so long as they are willing to learn and don't have trouble looking things up and/or asking questions. So long as the grammar isn't atrocious, we generally won't point out problems with that IC, unless the player has made it clear (s)he wants such errors pointed out for the sake of self-improvement. We personally tend to be strict on players' sheets so we can relax more when they get approved for writing IC. We've barely had any IC posts that needed to be rewritten using that system, and we've got a lot of players. Advanced isn't so fearsome a beast as many seem to think. So like [@Angel Vicky] said, jump in the deep end, [@BeanieBaggie]. Advanced might bite a little, but those teeth are all freshly brushed, so the bite won't be septic, nor will any limbs be bitten off.
