Matt Mower tells me that liveTopics 1.1 provides a backup feature that will produce an XML file of Post IDs and Topics. That settles one thing…
Next problem: Most of my Radio posts were created with MSIE’s WYSIWYG control. I need something that will massage bad HTML into valid XHTML.

Bryce: The easy solution is to surround each post with <![CDATA[…> tags; the XML parser will then simply ignore it. The hard way is to run each post through HTML Tidy http://tidy.sourceforge.net
