You know, the web site could be a great place for archiving - such as articles and newsletters, etc.
I am a great fan of the newsletter, I am not a fan of spreading it around to attract new members - somehow I am happy in a smaller crowd - not as a discourage any new members, obviously, but, why push the envelope? Once you have a large croud, you need much more structure - exactly what CDMAS was presented with. At that time, I think it stops being fun. Only my personal feeling, though. Not discouraging anything.
The newsletters could be placed as stickies for a while here and then archived at the web? I don't know how much space you have on the free web site?
