Thanks for the information. It does raise another question for me though. I noticed in Re^3: How to update a node? (readmore in code) that the raedmore tab appears to be case sensitive according to the second option below.
you can write <READ MORE> or <READMORE>
I know this is not the case with the <code> tag but are there other case/whitespace issues with the perlmonks approved tags, shortcuts, etc?
