tricky admin tip: user can't edit own node

Tricky!

If a node's "Input Format" gets set to something like full HTML or PHP, but the node's owner does not have permission to use that format, then the node owner can't edit their own node! The administrator has to change the node's input format back to something that the user/node-owner has permission to use.

I couldn't figure out why I wasn't able to edit a few of my ProRefactor pages. It's because I created those pages using Rich Text, which my normal user "john" account no longer has access to.
