Hi,
I don't like useless things, so I wonder why the "AIM ID" field is still there in user profile, despite the fact that the service was closed on December 15, 2017 (see: https://aimemories.tumblr.com/)
Same thing for Yahoo messenger, closed since July 17, 2018 (see: https://help.yahoo.com/kb/SLN28776.html)
Same fate it seems for MSN (Windows Live Messenger), since octobre 2014 (see: https://www.bbc.com/news/technology-28987797)
How can I delete these fields?
