MSN Messenger Polygamy tricks MSN Messenger into allowing users to run multiple instances at a time. It patches the executable of the instant messaging application, making possible to login into more than one account.
MSN Messenger is popular enough to have a respectable crowd of users. One of its disadvantages is the fact that it restricts user access to one account, which is slightly uncomfortable, to say the least.
Whether the situation requires that several people wish to log into Messenger at the same time or you have multiple accounts (one for friends, one for work, etc.), you need an application that allows you to run multiple instances.
In the same way that Yahoo Multi Messenger acts for Yahoo!, this application cracks the algorithms inside MSN Messenger, enabling multiple instances.
So, you and your friends are free to simultaneously run MSN Messenger from the same computer, at the same time. Usage is extremely simple. You just have to run the executable file, and then click the Patch button. If the operation is successful, you will be notified accordingly.
Just bear in mind the fact that sometimes crashes may occur with your MSN Messenger, because multiple instances on the same chat server are seen as "unnatural" by the computer. But it should generally work well.
All in all, use MSN Messenger Polygamy and you won't have to sign out and sign in again, every time you wish to switch accounts.
