Are you going to post these skins in the standard format generated by SkinMaker as a zip file on the MediaEngine website? I would like for you to.
Just have them in the regular:
SKIN NAME (DIR)
If you have custom fonts, put those outside of the SKIN NAME directory. Put them in the same dir as the .skn file b/c that way people will know what to do with them.
Perhaps I will make mediaengine copy them over automatically, but for now make sure to do it this way. You are currently the only one skinning, so if you have any requests on things that I could skin on M.E. you would "like to be able to change" let me know.
