Windows Live Messenger will be completely obsolete as of 31st October. Thats in china - it got killed off in march 2013 everywhere else.
As a result, any questions to do with WLM will be quite useless except in a historic sense. The software is entirely useless without the underlying servers and protocol, and any questions to do with them will not be of any use to future users (Unless someone installs WLM, and complains it dosen't work, of course).
I believe editing the tag wiki to reflect the EOL-ness would be a start. Do we get rid of the questions under the tag or leave them for historical purposes? In short, what should we be doing about dead software?
