Protected Source

First of all, clear your cache.

I tested and it works for me, it removes the php tags from the WYSIWYG mode and then puts it back again after saving. A small icon showing that there's hidden code there would be great but the first thing it's to make sure that things work fine and then make them beatiful. Maybe Frederico already has this done in his source, we'll have to wait to see when comes the next version and what does it have in it.
