yeah if i Upload something it will have proper labeling just unpack it check it and you won't need to change the name by much

Here's an idea: Customs FTP. There people can upload their fixed builds without a problem there, but nothing as far as a full fledged custom OS.
And a member's release forum. There if somebody were to release a build, they can announce it there, and there won't be as much trouble with labeling and such.
