have tested it on my servers. (Mangos) 2.4.2 & 2.4.3.

Now To get to the islands type the following GM commands:

Programmers Isle: .go xyz 16304 16318 69 451
Designers Isle: .go xyz 16303 -16173 40 451

Now have fun and do .gm fly on and .mod aspeed 10 and go sick exploring.
There is a bunch of custom events and mazes that are hosted there so use it how you want.

Watch out though, you need a certain patch so it doesn't crash your woW. Can't find the patch at the moment. But i'll look for it. And post it here when I find it.
