Ok, this may be a little out of the scope of the project, but I'll post it here for you to consider anyway.

Say you have a sign with the following:
MyWarp - Header
NameOfWarp - Name of this particular warp
1 - Number of the warp sign, corresponds to another sign with the same setup, but the number 2 instead.

So the above sign would correspond with
MyWarp
NameOfWarp
2

You could even have it cycle between more than two signs.

And what is the difference to the existing way? I mean, what does the number change?

Well, what I meant is that the signs don't exactly correspond to warp points, rather, the signs themselves are linked.
You have two signs, and clicking one takes you to the other-- a 2-way teleporter.
The numbers (and the rest of the lines, for that matter) are just there as an example of what could be wrote to link 2 signs together.

That was just a bit of brainstorming, though. I guess brainstorming should probably not occur when one has gone without sleep for long periods of time, heheh.

Okkkay ... I think this is something for an own plugin, as it is completely different purpose.
