UPD (Dec 15, 2018): We’ve got Terra Messenger 2005 to work with Escargot! Here’s a patching instruction by @Dung: https://wink.messengergeek.com/t/terra-messenger-2005/8881/9
Recently I found this interesting unofficial MSN client named Terra Messenger 2005 by Terra Networks, S.A. that based on MSN 5.1.0639.
I tried to patch it for working with Escargot, but failed.
Btw, here are some screenshots of Terra Messenger 2005 by Softonic, where I downloaded this program. It looks like official MSN client with slightly changed design.
It also has a website, which is still working, but it states that Terra Messenger discontinued as of February 28, 2012 (?).
Any thoughts of it?
