Well, I have been looking for a nice all in one messenger and I first came across Gaim. I had nothing but troubles with this (probably works a lot better on Linux) and gave up with it quickly. A little after that, (month or so after) I came across this application, and I have to say that for free this application is wonderful.
When you first run the application you get a simple little wizard that comes up, allowing you to add all of your accounts to the program. Once you do that, you will see all the people you have, in all of your accounts, in one program.
When you run the program, you may notice the design is very similar to MSN Messenger. For example, the window that pops up over the icon on your task bar notifying you that someone has come online or that you have received a new E-Mail, looks almost the same as in MSN Messenger, except for the little Easy Messenger logo appearing in the corner instead of the MSN Messenger logo. Another example would be is that the chat windows also look very similar to MSN Messenger's chat windows. Basically the whole point of this paragraph is that this program, has functionality and looks good. :-)
So in conclusion, I highly recommend this program to anyone who uses multiple messengers, because there are some definite advantages to this program. For example, some other good things about this application would be: it's only a 250K download, it will use less RAM than running all of the different Messengers at the same time, there are no ads in the program, and finally, it's all free.;-) Also, don't let my score scare you from getting this program, I just had to give it a 3.5 instead of a 5.0, because of that big flaw. I have to keep my guidelines the same for everything you know ;-)
