I didn't see this mentioned yet but not too long ago I joined a pretty good T/A site, even though I'm not much of a Facebook fan myself, it was active enough so I joined. It's called Historic SCCA Pro Racing Trans-Am Series Fan Group & Here's the link:
https://www.facebook.com/groups/109038482465812/I have recently become a fan of Google+ because it's a social network without all the ridiculous ads, redirections, difficult processes, etc. and it's integrated with most if not all Google services like Youtube, Chrome, Gmail, Talk, Translate, etc. It's the second largest social network on the internet and I believe if FB wasn't so old and well established, Google+ would have buried it by now. Anyway, I waited to see if anyone would open some type of community within G+ that would focus on Trans Am racing so it would get the audience and recognition it deserves but no such luck. I waited and waited but as a Trans Am racing finatic, I just couldn't wait anymore so I started a community called Historic Trans Am Racing Enthusiasts over there.
I just want to be respectful here and say right now that I have no intention of stealing attention or material, info or anything like that and if I use something, I will generally just guide people here with a link. This community I started is not to steal anyone from anywhere but to rather just open up more awareness, conversation and sharing of info for T/A racing. In fact I've listed sources on the main page and you guys are at the top. If anything this will guide more people to your site/forum. Anyway, please come and check it out.
Having a Google+ account is as easy as opening a free gmail account.

I'm not expecting participation. I'm also totally willing to accept accountability from you guys or anyone else that thinks I'm doing something wrong that would affect others.
