Another wonderful article written by Lora at What's new. I'm one of the lucky ones that is in her Messenger list and I can confirm than in more than one occasion she has given me very good advices using this communication tool.
I see sometime other people installing Aol messenger and other instant messengers but I prefer MSN Messenger. The main reason is because it's there, preinstalled in Windows. And believe me, I have used it as one of my Remote Tech Support tools many times. People usually do no like to install new programs in their PCs so to me it's easier to ask them to use what they already have installed.
