I asked about this sort of thing a while back and I got this:
"Currently, there is no way to put plain HTML on your CafeMom profile or homepages.
For now, we are not allowing all types of widgets to be added to CafeMom. This way we can make sure that everything added to the site is secure, and will not cause any problems. If there are particular things from other sites that you like, let us know and we might be able to add them.
< The CafeMom Admin Team"
so basically we are only allowed "approved" widgets on our web pages.
