I don't know if this has been posted or not but this is a very helpful addon for opening tickets on servers. You sometimes have to relog or recall port to get the tickets though but it works.
you just have to /join gm_sync_channel
Filebeam - Free Fast File Hosting
and if you don't know how to use addons
unzip the file with WinRAR or something. then drag the folder to
WorldofWarcraft -> Interface -> Addons folder
delete your cache folder
restart wow
click the addons button on the character login page.
make sure it has 'load out of date addons'
make sure MY_MASTER is selected.
the icon will be on your minimap. it's pretty self explanatory.
once ingame type /join gm_sync_channel
hope this helps some people.
