As most of us already know, microsoft is going to shut down their msn messenger versions that are lower then msn messenger 5.
But this also affects Trillian, Imici and Odigo (3rd party programs) meaning you propably won't be able to use them anymore. This will take place starting from the 15th of October.
Security update or easy way to get rid of these programs or payment trick?

In the terms of agreement of msn messenger is a line added where it says that microsoft has the right to ask money at anytime for new updates or that otherwise the consumer who doesn't pay for it won't be allowed to use the program any longer.
