Laptop, Windows 7, Chrome, all up to date everything.
I want to tag users in posts here. I type @ sign and start typing their username....as I would if @mentioning someonw on twitter.
Sometimes the name recognition engine kicks in (though very slowly...zzz wake me when it's over......) and sometimes it ignores that I started typing Name no matter how long I wait. Sometimes it works and doesn't work in the same post.
