I would like to know if there is a way to remove a contacts email address that shows in the To: section of the IM message window for that contact.  For example John Doe is one of my contacts, and I have changed Johns contact name in MSGPlus to Speedy, and that show up fine in the contacts list.  I also had John Doe change his Dsiplay Name under his Peronal Settings to Speedy.  When he and I are logged on and sending messages backand forth i notice that his contact name in the top of my MSGPlus chat window where is says To:  shows the chaange made to Speedy, but it is then followed with <John_Doe@hotmail.com.

My question is can the <John_Doe@hotmail.com> be removed from this line in the Chat window?  Basically I would like to remove any refference to eamils over chat unless specifcally requested, just my personal prefererence. T
Thanks for the assitance
