They’re all over the place recruiting all the time. I’m in four trade guilds that do all the above and more. Like the chat never stops and there are almost daily trial events etc requiring voice chat. People constant grouping for whatever activities make sense. One guild does events nightly where the GM assassinates people and the group loots the bodies. Easy money. They do skyshard runs in Cyro (which I’m going to take advantage of soon). All kinds of stuff. Just keep playing and respond to zone chat invites. I’ve found that the really accommodating guilds require weekly dues. But I came to those guilds for the traders and was pleasantly surprised by the number of fun group events they organize. Your mileage may vary. Point is, I never did anything beyond respond to zone chat guild recruiting invites and pay my dues. If you don’t like a guild, leave and join another!
