Union PM Problems

Im the leader of The Resident Evil Union, in the past couple of weeks I have been trying to develop a Union Newsletter that will go over the GameSpot PM system, last night I was working with it and experence a few problems, first I want to send the PM only to the REU Officers, but instead went to everyone in the union, members included. Also the PM was sent 3 times, and I had problems with it not sending and I click the send button three times, but the third time is when it worked for me. Also I noticed a few things only worked for IE7, I have a picture that is transprant with the background and when I went to go view on IE6 i noticed that it had a black background.  Also I really hate that when you go to preview the the pm it has no boundry but when the PM is sent its has a certain boundry (I hope that made sense to you). Also Im finding it harder now that my union has thousands of members to find certain members when I try to promote new people to an officer position.
