Hello again!
I have a decently compiled .FGD (mind you, its not perfect, but it's all feature complete) and I personally use it to make my mods and such.
Its a derivative of the one on the Valve developer site combined with the superior version of the more up-to-date version of Dongs (who made some cool maps for the game). It also adds all the guns and other things such as cut content (that part is commented out though due to not having SDK access).
It would also help the Entity Wiki if we have more hands on the CS single player wild ride!
