Anyone have feedback on Audiogon's Insider membership?

I'm curious about joining but Audiogon's Insider but its information about the feature is a bit conclusory.  I'm very open to paying a fee to have access to a forum of paying members (for numerous reasons).  I'm wondering if the Insider has critical mass to support the forum, how folks like it, etc.  

I noticed that a previous discussion thread on this topic has been removed.
