I believe msn is the best chat program available today. They upgrade the program on a regular basis so you arent stuck with the same boring features. They are constantly adding new things, making the program essential to you, the consumer.
Msn Chat is my favorite because first of all I like the ability to choose who I will chat with and whom I will not. You have to approve any requests to add your nick to anyones list.
Your friends that you have approved will appear in a list within the program and you will be able to see with a quick glance who is online and who is not. A separate window pops up when someone on your list signs on telling you they are online.
Another feature that I like is the away settings. You have one for away, busy, be right back, on the phone, out to lunch and the best one of all appear offline. This feature is nice if you really dont feel like chatting but do need to talk to one person on your list. This way you can sign online whenever they sign on and you dont have to be bothered with other chats.
A fun feature that msn has are all the symbols that you can use. They call them emotions here. You will find a variety of faces, smiley, frowns, tongue out, sunglasses, surprised faces, etc., along with stars, hearts, broken heats, phone, cake, camera, roses, and more! You can express yourself here not only with words but symbols! It just adds some fun to chat!
Msn also has different fonts, you can change the size as well as the color of your print. I like this feature! You can easily distinguish in between what you say and your friends!
You can send an email to a friend with the click of the mouse, start net-meeting, send files and/or photos, or make a phone call. You can also have multiple chats, and invite others to your conversation which is a nice feature. I belive this is limited to 5 per chat session, but not sure. I dont usually what with more than 2-3 at once anyway.
I find the service is very good and rarely not available. I highly recommend this chat program to anyone that likes to chat!
