change the web-based subscribe behavior to be like the email-based subscribe behavior
When you try to subscribe via the web, it sends you an email with your password in it (bad!) and then forces you to enter that password into the website. Awkward!
It should just send you an email, with a link you can click or an address you can reply to. This is what happens when you send mail to listname-subscribe@lists.riseup.net
