All I can say is, SUEET! It is a project that integrates best of breed Open Source .NET software to produce an online community suite. That makes it a direct competitor to Community Server and, to a smaller extent, mojoPortal.
Iâ€™ll be looking at the possibility of migrating That Stupid Club which is currently running on CS to Sueetie. CS was nice, and for a while was the only choice, but it is just too big and too complex to customise easily.
