FWIW, in my own interwebnet applications, I don't use radio
buttons, I have links which the user clicks to immediately
submit their choice to the server.
What you want to do is use single-submit-button forms, not links.
(Eg. you have one <form> for each action rather than a link, with
a submit button as UI to trigger the action.)
You can achieve this in a couple of different ways.
The easiest is probably to use the <button> element, and style it
(which works even in Safari, as far as I remember) to make it look
like a link. The other option is use AJAX. So you could, on your link:
<a href="/settings/subscribers_only" onclick="magicFunction
(this)">Accept messages from Subscribers only</a>
(where magicFunction uses AJAX to do a POST request with some extra
bit added to say "this is an ajax request: really do it, and then
update the link to say "Accept message from All", or whatever)
The other, arguably nicer, option is to do such a magicFunction on
the input element itself. (ie. so when the value is changed just do a
silent ajax POST, showing an error message on failure)
Both options could easily work for non-Javascript scenarios (the
first by showing a "Do you really want to do this?" form, or
whatever; the second by ensuring you can do a traditional full-page
submit of the form).
