Welcome to the forums, Gaara, brother to Haileo. xD
That's the beauty of typing on a forum, my friend. Nobody will really ever know if you're a slow typer. Just take as long as you like making replies and then post them. Unless someone has been stalking you, they would just assume it only took you a few moments. ;D
(As .Oblivion said, your speed will increase while being here any how.)
You don't know what to do around here? Well, I just don't see how that is possible! There are so many sections for you to explore and voice yourself in; just surf around until you find a nice discussion that just begs you for your input.
(I suppose it can be intimidating to post the first couple of times, but you will adjust.)
Well, it was a pleasure to meet you, Gaara. If you ever feel like having a chat or anything, my profile is always open to a private or visitor message.
Take care now.
