Well, apparently some of the html tags that are supposed to be supported, aren't. And some aren't fully supported like they should.
-<p> does not work
-the only <font> tag that works is color...and not always. (I did <font color='#FFFFFF'> and it made the font black. o_o)
-<img> does not work
-sometimes the background is set black even though it's not set to. O.o
-sometimes the bgcolor attribute of <body> does not work
This may not be a universal thing, but it's happening for me. o_o
