Who should I be looking fro when I log on to join the guild?
I assume you're talking about the Star Wars The Old Republic guild?
If so, your best bet is to join the Brotherhood channel in game and ask if anyone is online who can add you to the guild.
To join the channel, in The Old Republic, right click the chat tabs, click Create Custom Channel, and then type Brotherhood.
For more info on the guild, check out the wiki article
Edit: And I hadn't noticed this was IN the Old Republic area... ignore the first line
HAHAHAHAH Thanks! I will do that when I log in
