Huh... Never even thought about this, Lol.
To be honest, I would have to say that I'm not much different I suppose between in-game and on the forums.
In-game, On some occasions , I do punctuate and all that fancy stuff and I wouldn't even realize it. I mostly just watch unless someone engages me into a conversation.
On the forums, I'm becoming slightly more active, even though I may not respond to every post out there, but I would read some of the new ones that come out.....I guess I'm fairly balanced between the two.
With that said, it will still stand the same for me when it comes to people saying 'Hi' to me or whatever I suppose, Lol. ~
