Does the JoomSEF component work with the built in archive system in Joomla?
I've got a link on a page that currently goes to ".html" which should be going to the archive page. Any ideas?

Slight bug in JoomSEF - it doesn't pay attention to whether menu items are in the trash. Therefore, if you delete a menu item, but don't remove it from the trash (or haven't got round to removing it from the trash), the SEF URLs will reference the deleted menu item.

It's not a major issue, but it shouldn't be hard to correct.

Thanks for a great component, and I am waiting eagerly for the developer docs to build SEF extensions!
