Sounds good! PigLick's joined us a couple of times from Australia; you'd probably be around the same time zone, right? As far as being new to Arma 3 is concerned, we're a friendly bunch and still pretty new to the game ourselves. I'm happy to help you set things up (i.e. mods, Teamspeak 3) if you run into any problems.
We haven't yet set a date for the next Arma session, but I expect it'll be either be Sat 22/7 or Sat 29/7, 4pm UK time. I'll post an update once we've decided.
