“Read More” is handled by a filter on post_text.

Is this pluginable, or something that can be done via templates in my-templates?

The RSS feeds display topics instead of posts. This involves the bb_rss.php_pre_db hook, the $bb_db_override global, and some voodoo.

Nice to know, this helps solve some issues I have on a site design I am working on.
