There is this program called Messenger Discovery, it lets you run more than one instance of WLM (which means have more that one of the program open at a time) and much more, so you and your friend can both be on at the same time. Here is a link to the site

Just click on the download button, and if you want to you can check the site out more and see what else the program has to offer.
