Um, from what I've gathered from this and other forums, it sounds like you didn't ask for permission from the authors before releasing this. Since the vast majority (perhaps all) of the maps/models/mods etc. used were not made by you, you have to ask each and every author before including them in this mod.
You must know that you HAVE to get author's permission unless they explicitly state in the Readme file that they don't care what you do with their models/maps/mods or whatever it is. If they say no, then you cannot use them lest you incur their wrath and get into legal troubles. I know it's time-consuming, but it has to be done for legal issues. Not to sound harsh or anything, but I've never made a mod in my life, but I know to contact the authors and ask for their permission before you go ahead and use their work.
