New Sig request

Well, new to this signature bit. Btw, thanks for the grand service you all provide!!!

I'm not sure what a good image would be for the name Dark Trainer (got the name as I am a trainer in real life.)
- I'm big on stealth.
- Wasn't sure if there was a way to make an instructor/professor look stealthy.
- Maybe coming up behind someone with a ruler (instead of a knife) at the throat.
- Even a chalkboard somewhere in there.
- I play Day of Defeat alot too, so a little war background would be nice.

Feel free to play with it, I'm open to suggestions

If you need more info please let me know...I'll try and get something.
