group notifications

Something is seriously weird with my email notifications from g.d.o. A few weeks ago I changed my email address on my d.o. profile, and now I'm getting notifications randomly sent to the old AND new address!

I've tried to use the "My unread" and "My group" feed links under Group notifications in the right-hand column of groups.drupal.org so that I can catch up on my drupal groups in Google Reader. I'm logged in to groups and gReader.

The feed I get when I click on "My group" is http://groups.drupal.org/group/mytracker/feed and it's not at all particular to the groups I've joined. I get subscribed to recent posts across whole site.

I can't get Google Reader to subscribe to "My unread" at all.

I get a permission denial when I click on the notifications link.
