I just made this new mobile/DSi website called Texter Net which is basically like a social networking site. It has forums, chatrooms, a shoutbox, quizes and lots more other fun stuff. I already have 5 members... it's growing at the moment. Please press new-user on it to create an account and start chatting free today! The URL is http://texternet.onmbl.net so join, join, join! Loads of SDK members have it.
PS. My username on it is Land6 so add me and join the site!
