I just discovered a couple formating tricks. You can bold words when making mnemonics by using asterisks on both sides of a *word*. You can also italicize words using underline marks on both sides of a _word_.

It doesn't work on the Forum but it works when making mnemonics.

You can also add pictures using the img: tag (and also for custom definitions).

I tried but it didn't work.

Like so: img:http://www.whereeverontheinternet.com/blah.jpg

Thanks, I was doing it wrong.
