blockquote was in there; I just hadn't allowed for 'type' attribute. Fixed.
Here's a full list of simple tags:

Here's a list of the complex tags with attributes:
'a' : href name target
'colgroup' : align span valign width
'font' : color size
'ol' : type
'p' : align
'table' : bgcolor border cellpadding cellspacing width
'td' : align bgcolor colspan height rowspan valign width
'tr' : align valign width
'blockquote' : type
I fixed the disappearing 'post's too. :-)
