Unable to stop email updates

[notklaatu]

I was getting email updates on a community that's been discontinued.
There was no Unsubscribe link in the email, so I logged in to Savannahcrm and looked for a way to stop the emails.
I found a place in my Settings to leave or end the community (I don't remember the wording), and so I did that.

I'm still getting the emails, though.

When I log in to Savannah now, I get a screen telling me that I'm not a part of any community, and so no settings are available.

How do I stop the "Here's what you've missed in blah community" emails from "SavannahHQ <[email protected] via amazonses.com>"

I'm also happy to just close my account with Savannah entirely, not out of malice or anything, but because my job doesn't involve it any more, so it seems tidy to close my account. But I can't seem to do that, either. Every time I log in, I just see a screen alerting me that I have no communities.

Here's what I'm getting when I try to adjust my email settings.
