"But why?"

Why not? MSN Messenger was onve the ultimate king of instant messaging and social networking programs, in a time before Facebook, Skype, Discord, or Twitter. But then Microsoft bought Skype in 2012 and thought that owning two seperate chat services was redundant, so MSN was shut down. Which is a shame, 'cause even though it might not have the latest features, it still is a good IM platform. Now several people are working on reverse engineering a server for every major MSN version, and you can chat with people all over the world right now!

"But how?"

Escargot is a custom-written server built to recreate the older MSN Messenger server architecture, used back when Microsoft still had the servers running. The code to recreate the servers works for some versions of MSN, but (as of writing) WLM 2009 and 2011/2012 don't work, since those versions run on different protocols and use different technology we have to reverse-engineer. However, all of the code is fully open source and on GitLab, so feel free to contribute!
