STOP the Boost Your Browser etc pop ups!
I don't mind (well, I do, but...) seeing your YAHOO THIS THAT USE YAHOO pop ups when I first log on to the Group where I'm an assigned teacher. BUT...EVERY FREAKING SINGLE TIME? Read. My. Lips. = Not Interested. For that reason alone--that you cannot conduct business in a mature manner--I'd not choose to use your service (and no, I sign on as a hired teacher to a company using groups. Not my choice.) I cannot even recommend you to similar venues for that reason. Unprofessional.
