Regarding MC360, the SVN is the best place to download the latest version. Towards the end of this week, we will release 1.05 which will include the current SVN tree, this is likely to be the last 'version' numbered release of MC360. Everything will be based on SVN numbers from the official XBMC Skinning SVN where MC360 now recides.
I myself, will be returning to skin in the fall, specifically September/October. I plan to finish 'eX' and have that ready before Christmas. I would also like to get the 'THR33' Skin release before Christmas, but we will have to see how things pan out. I look forward to returning to skinning after having some time away from it and I hope that the forums will perk up again with chatter about our new skins.
