Thanks for the info. I'm working on a Ruby on Rails tutorial book (<a href="http://www.railstutorial.org/" rel="nofollow">http://www.railstutorial.org/</a>), and some readers have started agitating for a forum. Having used Google Groups for my previous book, I was <i>really</i> reluctant to go down that hellish road again. I took a cursory look at Zoho, but didn't drill down very far. Knowing that jQuery is blazing a trail there makes me much likelier to give it a try myself.
