I like it, but maybe the ad in the left corner of it should go?
I think you can turn off ads by clicking the little 'i' on the right side of the ad section... if you can see what I mean?
Also I think you can turn off the sound by going to "? Friends Online" then the volume button next to the minimize on the top right of the pop-up.
Another (small) issue - quick links is covered up by the aquariums in other people's signatures. Maybe fix it so that it appears on top instead?
Does this only work if your friends are signed in on the meebo bar as well? That's probably why it isn't showing whether some friends are online - probably because they haven't activated the feature yet. It's like facebook, you can pretend you're actually offline... >XD. But I reckon this is kind of redundant because friends can see whether you're online by going to the my gaia page anyway.
