Spawn delay
 

is there any way to delay the spawn of a certain team?

Well one or two maps prevents spawning until a condition is fulfilled (ff_fatties, for one). I don't think it would be hard to prevent spawning until a timer has run out. Whether or not it would have to be a generic timer over an individual timer, though, I don't know.

Apparently you can do it for individual players by using:
Figure out the timer yourself.
