All tags supported by the forums are also supported by dm. There's only one or two tags that aren't listed. Specifically, the table, tr, th and td tags aren't listed but are supported. However, you need to take care when making tables for dms or posts. Any new lines between the actual table tags will get converted to br which causes browsers to render the table incorrectly.
Pretty much any tag that can be used for xss or abuse is stripped. That includes css tags, script tags, div tags, etc. Lots of tags.
