You know, now that I've thought about it more there is QQ. It's a Chinese / International instant messenger that looks eerily similar to MSN back in the old days. I thought it seemed nice, though I didn't use it long since I had no contacts on it. Its also on Android, iOS and Web.)
Now that I remembered it, I have it opened up now so if anyone wants to add me on there, I'm Yukupo.
(About Pidgin, it's not a bad IM. http://www.pidgin.im A little plain and it never did support MSN in all its entirety but I was on there a lot toward the end of MSN days because I thought the MSN software got worse and worse with each version. Oh classic MSN days how I miss ye.)
