We are looking for an instant messaging software for our team network that is not web based. We want the ability to send instant messages from one another on a Windows plateform (I personally use a Mac with Parallels and XP Pro). We need something that is very quick so that when we have a phone call on the line our call coordinator can send a fast message saying "Judi, Home Buyer Bill Jones is calling about XYZ home for sale". We used to have an instant message software 5 years ago called winpopup or winpop which and this program worked great and was part of an older Windows version.
I see a tremendous value in getting this instant messaging system up and running again. I want to be clear that this program does not have to be free but it does need the ability to send a group message to all users on my office network or an individual team member from a pull down menu. Your help and suggestions are greatly appreciated.
