If you are interested in the Cheesecake project, you can now subscribe to two mailing lists: cheesecake-dev and cheesecake-users (thanks, Titus!)
In the near future, most of the discussions will take place on cheesecake-dev, since the Cheesecake/SoC project is in full swing.
Michał and I already posted a couple of threads with feedback that we got from the CommentsPage on the Trac Wiki. We'd love to get more feedback, so please don't spare us! You can also add ideas to the SummerOfCode06 Wiki page.
