Descriptions for sure...Most of my posts tend to be the character either talking or their thoughts on something. Other then that, can't really think of anything offhand.
Well ... I'm tied between two things. Despite roleplaying for four years, opening posts have always been a pain for me. Mainly because of my perfectionism, but also because I sometimes worry about the opening post being too long and driving off potential roleplay partners.
The other thing is large group roleplays. I'm a slow writer (due to the aforementioned perfectionism), and I tend to get left in the dust in large groups due to that. Probably why I don't join anything more than a four-person-total now ...
A fresh and growing community.

I find it a bit annoying to type a really long post during an action scene and then getting ninja'd to the point where you post doesn't make sense anymore.
