Hi mate,
RTFM is an internet acronym that stands for Read The F****** Manual.
(It's not really meant in an offensive manner though, just as 'did you check the manual??', hence the winking smilies).
In my post above, the text is a link to a page in the MySQL manual that details the usage of foreign keys in MySQL. Here's the link again:

Hope this helps.
Regards,
Matt.
