Happy to help! :) If you have any other questions, feel free to shoot me off a message. Also, your picture in your sig seems to be broken.

Usually, in most RPs, there's a loose posting order that tries to get people through a rotation so most of the players have a chance to reply again before starting over, but it's different from game to game, and most GMs are pretty lenient about posting schedules. Typically, expect to do 1-3 posts a week, depending on the game, and more or less depending on how busy it is. 

Either way, welcome and enjoy yourself!
