EagelX is just a little kid from Israel and usually if you tell him after the first time, to ask for permission before hand, he does. At least he does with me, as I've allowed him to take a few hops with me.
As someone who's name appears usually near the top of the list, I get bombarded with these join pop up windows a lot and I agree with BGB, the default setting should have it appear in the message window instead of the pop up window.
