Ok, I know how to set up a 2 set spawn jump.. but is it possible to set up 3 different spawn points? and if so.. how do I do it? I've been thinking about it but I just can't figure it out... Any help would be greatly appreciated!

It's possible. Technically in belfort I have 2 flags of advancing spawns. To compensate for this I have it set up so that half the main spawns match up with one flag, the other half with the remaining. So:

Allied Spawn:
8 tied to The Tunnels
8 tied to The Estate

Allied Spawn:
8 tied to The Tunnels
8 tied to The Estate

The Estate:
8 tied to Allied spawn
8 tied to Axis spawn

The Tunnels:
8 tied to Allied spawn
8 tied to Axis spawn

But you could organize it any way you want. Because in either case you're going to need to leave a possibility that a team would have both flags. Also you could have it set up in such a way that there is no re-cap of a flag allowed so in effect you'd be able to make a linear push type map that would allow for multiple spawn movements without having to worry about left over spawns.

Dunno if that makes much sense, but it works.
