I notice that the site has slowed down. It seems like there are fewer participants (fewer professionals from the industry). i still say that if the all the topics were easily accessible, it would increase topic discussion (even if it slows down load time). Is the board promoted in your other publications. The site has never recovered since the last shutdown. Is there a way to contact former members to invite them back.
Just some constructive dialog, and brainstorming.
Have you thought about doing a weekly podcast with the top forum topics?
