Nostalrius Begins - Quality wow vanilla realm (1.12)

If you have accidentally left one/more main chat channels rather than that personal one you want to leave, here are some useful command to rejoin them:

/join General
/join Trade
/join localdefense
/join worlddefense
/join lookingforgroup
/join guildrecruitment

You'll know you are in the right channel from the colour of it and some of them usually have the zone where you actually are in their names (e.g. "General - Durotar").

...and I cannot stress it enough...
write LFG messages in Looking For Group channel (/join lookingforgroup) and not in General if you can, please !

Thanks
