I don't see why you are against it. Totally blocking it will def. be counter to your wish of 'i want her to build relationships'. All her friends will do it this way. So you are blocking that time with her friends, unless you expect her to call her friend so she can ask what's being said in the 5 way AIM chat.

I could see why you are against internet chat rooms leading to AIM etc, so block those and let her only add people to AIM that she knows from school.

Or if you are worried about her going brain dead from sitting there doing nothing all day just set a time limit on it.
