<> SirLoin,
If this is due to the pop up window you get , their is a way to get rid of the pop up window.
type .showjoin0 or it might be .showjoin 0
in any case when someone tries to join you , you will not get a pop up window , but in your text buffer it will show.
only draw back is that you have to type this everytime you enter the MA .
As for accepting I dont remember , but I'm sure someone knows.
