Sounds like a great idea, my only problem is that I'm from England and with the server being somewhere in America I get occasional lag spikes and I have an 'internet curfew' so I probably won't be able to take part much with other guildies from America. :/ Still have characters on their I plan on using because I'd rather have some interaction than none at all.
I'm on Jedi Covenant with a german/english/american guild.
Its not huge but we have an allied guild that lets us fill groups fpr HM FP runs around 8pm GMT
