Actually, the reason you may not see as many posts is that most of the members are signed up on the mailing list and communicate that way... You can choose to either recieve each reply email as they come in or as a once daily digest of all the emails for the day. The second option is the one I use... But in this email forum is where the real questions and answers are!
You should look into this... on the average there are about 25 postings a day! And all the messages are archived ans searchable!
