Embedding Html Code

I was just wondering if Pixar Planet allows for embedded flash icons, such as a countdown timer, to be allowed in a post. Is there a special tab or text code (like bold, Img, URL) that I can use, or is it simply not possible?

I don’t think it’s possible to embed HTML in signatures or even on this forum. I think we only use BBCode here. Phileas might know the answer to that question more than me, though.
