I have six Gmail invitations up for grabs but they aren't free. I want to hear stories of an IBuySpy/DotNetNuke/Rainbow/etc implementation you have done in a real world environment. I am even more interested in portals you have written to replace the previously mentioned apps and the approach you used. I will give the invites to the best stories. Email them to me or post them here.
Sorry, all the Gmail invites are gone. Thanks for the stories.
