Jenn is correct that is the fastest way to find out what you want to know. I took a quick look and here is a list of members who posted over 10 times. You and Jenn are well ahead of that number!

Now don't expect me to do ALL your work for you! LOL You want to know how many posts each of these members have, do a simple search by user name only and find the number yourself.
And congrats on the big numbers! (Sounds like you just hit the lottery!) LOL
