http://live.pirillo.com - http://geeks.pirillo.com - After only a few days, we have well over 2,000 members on the new geeks.pirillo community site! We're growing like crazy, and many excellent groups and discussions are popping up. There are, of course, the occasional group that we need to delete, or even duplicates to get rid of. What constitutes a good group, anyway? How can you successfully lead your own community group?
