Here are some partial awstats for the forum subdomain. The Sept stats look pretty typical.
In terms of
unique users, we get between 1.5 and 2.4x of the total number of registered membership* visiting in a typical month. It varies on a seasonal cycle, as you might expect. The typical user visits the forum about once a week and takes in about 30 pages per visit. The average forum visit lasts just under 12 minutes.
*I don't know what percentage of those users are registered or not.
This attached chart represents just the forum area. The bonsaiTALK Gallery pushes a lot more bytes, but on a visitor basis it gets only about 20% of the forum's traffic.

Matt
