I've set up a mailing list so that people can talk about File Blaster and LabHand. It's a fairly low-volume list, so don't worry about your inbox get flooded with messages!
To join, cruise on over to Yahoo's Groups section:
http://www.yahoogroups.com/group/labhand
This is also where the File Blaster downloads are stored, ever since Apple started charging for iTools.
If you're not already an YahooGroups member, you'll need to sign up with them. I haven't been subjected to vast amounts of spam since signing up with YahooGroups, so don't worry about that too much.
