Herman - Saw your note - you didn't give much detail of anticipated uses, but as a SWAG, I'd suggest looking at Google Apps for business + a Google group
http://www.google.com/a My partner in Dallas runs a dedicated, feature-rich forum package for sites for us, but I don't think you would want the admin load of such a solution for a small business group. But, we have recently used the Google app's above for some ad-hoc, small-group tasks and they worked well. -- Bruce R
