may not because it has only the 2008 wttc series and the u.s. tracks with only formula masters and u.s. muscle cars. sadly they are not very popular anymore. of course i'm not a staff member so don't it off me but that's how i think of it.
It is summer time, Everyone is having a little downtime on the league front after the spring leagues. There are some series in planning. You will find their announcements in the Leagues forum -> http://www.racedepartment.com/racing-leagues/
May not be specifically based on RaceOn's content though.
I would suggest to wait until the middle of august because there is a Race Series league Called Nations Granx Prix who will start reviel it's upcoming season. Just stay tuned and you will find the Race Series league of your dreams.
