I worked with these guys for a little over 5 years, and it was in no small part responsible for where I am today, if anyone is on the fence about this, do it, you won't regret! 

Rule 2: Remakes of existing maps are not allowed, however maps inspired by classic DoD maps are encouraged.
Basically you can make maps based on or inspired by a DoD map, but no like-for-like copies.

As well as LATTEH's response there is also a brief guide written by the folk at NWI on how to get started with mapping for DoI.  It can be viewed either here on GameBanana or here on NWI's website.
I'm sure there will also be a whole bunch of help threads and discussions popping up here and on GB / the NWI forums once people start mapping.
