This has all the information you should need to run GWMultilaunch. Running this does not break any rules laid out by Anet. You can open as many clients as you want. Just be sure to make new folders and add the gw.exe in each of them. I hope this helps. If you have any questions please ask. (This was copied over from an old user of the forums)

Someone was asking for it, so I thought others might be needing it also since you cant get it from GWGuru anymore.
