Can anyone explain how content is saved, what file this is done by and where does Joomla find out what fields there are in jos_content and therefore know what to update? The last one's the bit that's got me, if I can find where Joomla's getting the jos_content table structure from then maybe I can add the extra fields in there, that I've added to the database. Doing a file search on "introtext" doesn't lead me to any SQL UPDATE statement, which I'd expect.
