Thanks, and for those, like me, that want to sign up with a regular mail account (say, like a fastmail account;) -- one can do that via the web at:

https://groups.google.com/forum/#!forum/jmap-discuss/join (ie: group-url+/join), or by emailing <groupname, spaces replaced with dashes>[e-mail].

The [ed:first, doh!] I tried (make sure you log out of google's estates first) -- the second I haven't tried, but works according to: http://webapps.stackexchange.com/questions/13508/how-can-i-s...

Note, that if you send a subscribe email, you'll be subscribing the from-email in the mail you send (I usually subscribe with unique addresses to lists and accounts, so that I can more easily see which are harvested/given away for spam abuse. So far linked-in, and adobe are top (the latter presumably due to the big account leak) -- and that's a bit of a hassle as all email clients suck ;-).
