I've got the settings on my MT set to allow HTML in comments. This seems to work most of the time. One thing that seems to reliably fail, though, is using a STRIKE tag or the equivalent span style of text-decoration: line-through.

Is this a bug or a completely inexplicable feature?

Sounds like the completely explicable Sanitize feature at work.

Thanks, girlie. I searched through much documentation before deciding to cast a note on the waters. I guess I hadn't gotten to that section.

You rock.
