I've installed the plugin in WP 3.0 (multi-site) and BP 126.96.36.199. I also installed the TinyMCEComments plugin (which isn't technically compatible with WP3.0+) because it allows some basic text editing.
The oEmbed URLS work fine as long as there is no other HTML code in the comments. Once any markup appears, e.g.
<p>, <a>, <b>, then the URL disappears. No box, not even the URL text will display.
Any ideas on how to combine oEmbed with formatted text? I understand that the point of oEmbed is to avoid using HTML and shortcodes, but I want my users to be able to add robust, formatted comments. (Heck, I would even like for registered commenters to be able to upload small images into the comments, but that's a whole other thing.) Thanks for your help.
