Remove MSN. Use the skypeweb purple plugin instead.
RIP
As per http://ismsndeadyet.com/ all versions up to MSNP22 died a few
months ago. We had a MSNP21 implementation, bought us two extra years.
Implementing MSNP24 is technically possible but also pointless given
skypeweb, and the authentication requires some fairly messed up crypto
and legacy old-skype-protocol servers. For a long time I tried to
reverse a potentially simpler method, and got fairly close, but never
completed that. I haven't done any attempts to continue it in the last
year, so I'm fine with giving up at this point.
