As a nooby to GTL, I can give a comment about getting my feet wet like this.
My first race on-line with GTL was the Goodwood event. It was the perfect intro for me because I was able to avoid the embarrassment of punting the others off track by using something controllable (good ol Mini). I was also able to mix it with others and didn't end up lonely at the back. And lastly, I really enjoyed seeing the big guys blast past (or off into the boondocks too
) so it gave me the incentive to learn to drive something quicker.
So I reckon it's a great idea for us learners. 
Good call Warren, thanks.
But there are also people coming in who don't have the driving experience you have in other sims and are not already a fast driver like you.
Don't get me wrong, it's all fine by me but I wouldn't want to scare new peeps off who are relatively new to online racing in general.
I also see how fast new drivers adapt to SJ races in GTL and other sims (watch for Tysie guys!) and the old crew also makes a great effort to make all drivers feel welcome and give them time to get aquainted with our events.
I too remember well how nervous I was both in close racing and looking out for fast guys that came to lap me in the beginning of my SJ life. I made mistakes anyway and got sorted out soon haha. It just takes some time, as I now experience in RACE.... :biggrin:
All in all, let's give the mixed races a good chance since it must be a lot of fun and we'll see how it is for new drivers eh?
Frankly, I can't wait, haha.
