We’re having a problem with forum search, sorry. I’m particularly sorry that it has driven you to Yelp! which is corporate and VC-funded, but it’s our job to fix this. In the short run we set up a specific search page that might help (if you can’t get this, let me know).

I can search the back end still, while we try to find a workaround, so if there is any specific topic(s), please e-mail me and (as I have done for one person already) I would be happy to send you various direct URLs.
