you call ppl by their real names
Done that!
...your best form of entertainment comes from AOL GC chats
I feel sooo left out! I wanna come, I wanna come!
when you want to or actually go to a gc meeting
Yes! I wanna. Kelly? Did anything happen with the big plan? (

-- just typed Navane's name automatically without even thinking of first item in list!)
When you actually try and relay a particularly humourous thread/post to your friends out in the real world. (I *almost* did that the other day...)
Done *that* at an interest meeting! You don't wanna know which post... trust me.
When you have a question/experience and GC is one of the first places you think of to ask/tell.
Where else?
When you know that the Chit-Chat forum is where all the loonies hang out.
Here. Present and correct.
When you understand Tom Earp's posts
Check.
When you puke from the GC Drinking Game
There's a GC drinking game? I'd better search.
When you have more GC Crushes then real life crushes
Possibly

I'm still hoping there's some GC'ers too shy to speak out
When you reply to a thread entitled "You know you've been on GC too much when..." and you have no intention of decreasing the time you spend on GC. As a matter of fact, you'll probably increase it because everyone is preparing for recruitment.
Proudly
When you can quote someone's signature (without looking at your computer) to another friend who uses GC when talking about a thread you both read on GC
Yup, at least one.
When you have figured out exactly how to post a picture on GC
Check
I admit it - I sometimes check my PMs before my email...
Guilty.
You're plannin road trips with a GCer you've never met to go see more GCers you've never met!
Hmm... slammin' idea...
you read this thread and think that almost everyone posting on it is still wet behind the ears

Nope. But that last one made me laugh!
And to add... you know you're addicted to GC when someone else sets up a thread for you on your special day to wish ya Happy Birthday.
