I just discovered that over in my Gmail account I have a few invites waiting to be given away. I can't think fo anything I would like more than some cool new PPC software so I'll offer my Gmail invites in trade. You could pick your own account name before Gmail goes public and all the good ones get taken!
Developers, all it would cost you would be a registration code.
If anyone else has a software license they don't use anymore I'd be glad to entertain those offers too.
Private message me and let me know what you've got and we'll see if we can make a deal! You can e-mail me too at greg (at) gregmills (dot) com
