I see that in WordPress 2.0, do_action('rss2_head') has been added to the header in wp-rss2.php.
In WordPress 1.5, I added my own <image> tag right after <language>. But maybe in 2.0, I should make use of rss2_head? What is that, and how do I do it?
[Edit] Sorry about the title. I didn't know escaped characters wouldn't be unescaped. Whoops.
