After raising a swarm of hornets with the new Community Server 2007 license model (and I was among that hornets, too) and all the feedback received on the official forum, Rob Howard has just announced some changes in the license.
Now there are 2 different scenarios:
For the non-commercial, they raised the limit of the free to 10 blogs, 15 forum, 10 photo galley, and added a "Personal Edition" which costs 99$ but is unlimited.
For the commercial license they changes the names of the editions and raised the limits to 25 and to 100 (for the Standard and for the Professional).
Communities that promote .NET (user groups, etc.) are eligible for free Professional Edition licenses.
Now I feel better .
