Are there copyright issues?

All Combat Mission mods modify the work of the original product, which is copyright Big Time Games.

Mods of these games are distributed subject to the terms laid out by Big Time Games, specified in their End User License Agreement.

These terms might be summarised as "you can distribute them as long as you don't charge for them", though you'd have to ask your lawyer for an official interpretation.

This site operates on the understanding that this is the case.

The mod authors may impose further conditions on the distribution of their work, though as far as I'm aware none have done so.

I would prefer for no mods to be uploaded here that have additional conditions imposed upon them. If you find some that do have these, please let me know.
