One can think about implementing "?Mailman integration" or something, but I find that rather overdoing it. Mailman is simple enough that you can add a clean subscription form to your ikiwiki site in seconds, just add:

<form action="" method="POST">
Email: <input name="email" />
<input type="submit" value="Subscribe" />

To your site and voilĂ , you are done! No more scary mailman subscription form! (Thanks to ?bgm for that trick!) --anarcat
