I dunno if it's the highest. Motti and I have been averaging 22-23 posts per day since the start of the site. That comes out to nearly Skipper's rate with ours being 66-69 posts in three days time.

Skipper, yes you can see what your rate is by clicking on "The Server Move is Complete" headline on the forum homepage. It will take you to a stats page where you can find your daily rate in the top right corner and the top 10 posters in the bottom right. There is other stuff there as well. To get on this page, you have to be logged in to the forum, not just the log in as you post option.
