I just moved from MB2 to MBS/MBC. One thing that I noticed is I can't seem to re-order the Media Collections as I could in the MB2 Configurator. Perhaps I'm missing something. In all honesty, I've not read tutorials or docs, so if it's in there, please feel free to throw out a RTFM at me.
Thanks, and I'm thrilled to be moving to a client/server solution. Can't wait for MBT to be available in public beta. Nice work all!
