Nana, I've got mine in my profile. But I don't know that anyone has ever IMed from finding it there. I've seen other members list their IM handles. I doubt it's a hacking/security issue. Probably more a privacy issue. Kind of like keeping an unlisted phone number. It's easier to screen Email than it is to screen an IM. I've had my AIM handle for 13 years. And because it's similar to a well know rap star and something similar to one teens emulate, I get IMed often by kids who think they know me, or typed with my in chat room, Yo, wha' up? they say. I have to tell them... I'm nobody's homey! Now leave me alone, I work online.
