No, because there will probably be new sprites (as far as I know there will be. If there are not, then it _should_ still work.)
New sprites won't be registered in the metamod.dll, which is the library file which makes Admin Mod Compatible with Earth Special Forces. It usually takes anywhere from 1week to 2 months for this to be compiled because the creator of Metamod is so busy.
Fortunatly I will be installing Linux on a second hard drive over the weekend, and I will be able to compile it from now on, thus getting Admin Mod working with ESF sooner.
Anyways, you'll see it in the news when/if I get around to updating Admin-mod. With people like Kid Devil around, it might be kind of nice to have ANY server with adminmod installed so that he can be dealt with in the manner that is necessary.
