Thanks Gangabass,

I've now confirmed that checking the boxes and submitting with JavaScript disabled in my browser (Firefox) saves my checkbox selections without a problem, so it seems that wasn't the issue.  I doubt JavaScript is used at all in Mailman's webpages, as it seems to work like straight HTML.

Why do you recommend WWW::Mechanize?

Thanks.
