Due to popular demand, I’ve created a new google group for discussion/commentary on Rapid Web Applications with TurboGears, yhttp://groups.google.com/group/tgbook
One nice thing addition to Google Groups recently is the Pages feature, which lets me put up wiki version of the errata for the book. Now if you find a typo, you can edit the wikified errata page yourself. I’ll try to go through that page regularly and update the main TurboGears book website with “official, sanctioned” errata. But, there’s no reason people should have to wait for me to verify something before they can benefit from it.
If you think of new pages which you think need to be created, you can create them at will.
