I joint-post too slowly. I need to remind myself to check a JP pad whenever I'm building a post together with someone else. Basically, when you're JPing, focus on it until it's done! A couple of days the maximum time it should be allowed to take xD
Don't worry Fox could give you lessons on how to draw out the time a JP takes.
Speaking of which, when I'm on an etherpad and JPing with someone I occasionally get distracted by PC and come back to like fifty messages asking where I've gone.
