Title says it all.
I am trying to work out what a "BBC Script" block can do, and what kind of content it can hold.
Is it a language or just text + Bulletin Board Codes embedded, or something else?
Googling anything with BBC in it tends to get swamped by the broadcaster.
EDIT, seems to allow me to create content with BBCode in it.
Is there a list of all codes allowed anywhere? I looked at http://www.bbcode.org/reference.php
but things like youtube and gvideo don't work.
