I'm interested in learning in what order plugins are executed also. I'm running two that interfere with each other:
1. autohyperlink - automagically transforms http://www.whatever.com into a link and firstname.lastname@example.org into a mailto link. (Just like this forum does, evidently.)
2. email immunizer - turns email addresses into numeric codes to try to protect from harvesters.
The problem is that the immunizer gets to the email addresses first, which means autohyperlink doesn't recognize it as an email address & doesn't work its magic. If I could make them execute in the opposite order, it'd be perfect.
It looks like autohyperlink gets its work done with add_filter('the_content','autohyperlink_filter'); and add_action('publish_post','autohyperlink_filter');. Email immunizer does a set of 9 add_filter(); commands, one of which is add_filter('the_content', 'email_immunizer', 9);. Evidently that's where the conflict happens...
