If you ask me, there's no wrong way to do it. RPGs thrive on the skills each player brings to them. Just write a post that you're happy with and you'll be fine! If there are mechanical issues, they can be gently massaged out over time. This is an acquired skill. Consider it like a real conversation--if there are three people in a conversation and one person makes a comment that either or both of the other two could reply to, whoever gets a reply in first speaks first in response to a thought. If others have gotten in before you, react to their actions. As much as it would be nice for RPGs to be smooth, there are bound to be some rough edges. Work around them as best is possible. For example, Ktala or greyjedi125 could both make a reply to the most recent post that I put up after getting some direction from spycoder9, which is sometimes the easiest way for him to update the game. It's just a question of who gets to it first. Also, regarding spy, his schedule is sometimes tough. However, he'll get back to you soon enough.
