They're is ONLY ONE bit of software now needed for connecting to VATSIM.. Now that SB3 (Squawkbox 3) has been released, you simply download and install. You dont even need a registered copy of FSUIPC for it anymore - it comes with it
With SB3 you actually see the traffic moving smoothly, unlike SB2 where it was all jumpy. You can watch how good someones landing is!
EDIT: I forgot to say that new pilots MUST visit www.vatsim-uk.org/newpilot
to avoid problems
