I'm going to stress the following things yet again:
1) Be mindful of headers and filling them out properly.
2) PLEASE read all posts... it comes off as rude when you post something and it doesn't jive with others' posts, making it clear you haven't been following along (whether this is intentional or not, this is how it comes off so if you can't read along, please speak up rather than do this sort of thing).
3) If you are going to be delayed for a length of time, COMMUNICATE IT! That is, post it up in 'delays and absences' or, at the very least, PM the person your character is posting against.
4) Don't leave characters hanging and then just up and move on them... they were probably waiting for YOU.
That is all.
And if I sound like a hardass, I apologize. But in a group RP setting where there is an actual overall story and plot involving ALL the characters, people seriously need to be mindful of these things. Characters' path cross and people rely on each other for things. So please use both common sense and common courtesy and please... communicate. Thank you.
