Ok cool. Yea I'm on GT5 most of the time. I haven't raced in the main GTLeague Season for a while now but I've hosted/ing GT5 series. The final round of the Enduro Series is coming in 2 weeks (GWES). You're welcome to join man. There are a few guys here that are active on PC driving sims.
Welcome aboard mate. You can find the info about joining out Sunday night league here http://raceonoz.com/forum/viewtopic.php?id=895 We currently have 2 rounds remaining in this season so if you can get your qualifying time in you'll be all set for season 6. There may even be room for you in the remaining rounds, that would be up to the division captains. Alternatively like Seido said, we do have other events going on that you're welcome to jump into any time.
