As burra and casie pointed out, you just check and uncheck boxes and save. There is a link to that with every email. If there is any email that we send out that does not have that, please let us know.
We are in the midst of overhauling a lot of our email stuff. One of the things we are exploring is "one click unsubscribe" - it is on the "todo" list, but I'm not sure how soon we will get to it. It seems that nearly all forums do not offer this. After all, this is not a mailing list, this is a forum.
In fact, right now, I
think our email configuration stuff is richer than
facebook.
I think we have a lot of people that have come and made suggestions for improvement and a lot of times we make those changes - or put them on our "todo" list. And, once in a while, we have people express their ignorance through hostility.
Thanks for making this image for us Olof!
