As I understand it you can post anything but an obj file. Good options are pz3, cr2, and pcf (using Objacon mover which you can get from the utilities section of freestuff here). Use pz3 and cr2 for characters who have no changes to their obj files. Use pcf if you've modified a copyrighted obj. For Morph target's you can also post obj's provided that you've stripped out everything but the lines that begin with 'v'.

Truth has no value without backing by unfounded belief.
