Question about dots in e-mail addresses

3.6.9 (© 1998-2010) Last time I ran a HTML5 tester (a few years ago, IIRC), it reported a few HTML5 features that worked, but mostly not.

It’s surprising how many web sites no longer work right in my browser, even with JS enabled. Mostly it’s just fucked up formatting and graphic images that don’t display, but also a fair number of buttons and clickable things that do nothing when clicked.
