It's not just about posts. The system calculates a wide variety of things. What you get points for:
Starting threads
Posting replies
Reading threads
Being an active member of a social group etc etc
The medals are awarded based on a combination of your activities, like you'll get an activity award if you spend a lot of time on the site, a community award if you start a lot of threads and spend time on the site etc. So basically, the more you use the forum and take part, the better you score and more chances of you getting a medal.
There's 10 medals to be won in all, and only 3 have been issued so far. Let's see who can get the others
MB, you're so far ahead of everyone else that you've reached the maximum of the system settings (level 100). If I increased it to allow you to work for medals etc again, no one else would stand a chance! You can rest in the knowledge that you'll probably carry the posting award for eternity though
