Be reassured: we understand (but easily forget, so feel free to remind
us!)

What is the opinion of audio captchas?  That is, do they actually
work, and are they a significant inconvenience even if they are at
least in theory possible to use for blind persons?  Google ReCAPTCHA
implements an audio recaptcha option, for example.

This is a continuing goal of mine, for sure, and I think of all
Mailman developers.  But AFAIK we're all equipped with average-ish
levels of the usual senses, so feel free to remind us of the
principle, and if you notice any specific issues for accessibility,
*please* report them.  We probably won't notice them ourselves. :-(

@self (or anybody who wants to check and implement :-): We should have
an accessibility tag (and probably a usability or ux tag to
differentiate the use cases) on the tracker.

No "if" about it, unfortunately.  But we do try to avoid mechanisms
that impose more pain on real users than on spammers.
