Very impressive! 400 members and still growing which is a good sign. At this rate the Matialtalk will have 1000 by the end of the year. Then it will be real exciting.
Here's a little something to put our growth in perspective:
I joined this board in September 2001, and I beleive I'm the 45th person to register. Since then, half a year, our membership has increased to over 440...nearly ten times the amount of registered members since I joined. This also doesn't include banned users and pruned accounts.
