The project mailing list is on its way! I heard back from the University's IS department, which oversees the creation of new mailing lists on the campus listserv system. They have heard the cry, and hopefully we'll have a mailing list by the weekend.
Earlier this week I requested an arete-user mailing list address here at the University, but have not yet heard anything about it. I have a sinking feeling that the request for setting up the project mailing list could be denied, which would open up a new front in infrastructure requirements for the general UMFoundry effort.
The good news is that the blog got a face lift last evening, and is looking pretty sharp. Once the mailing list goes online, I'll report with updates.
