Hi 
Drew from TDF recently pointed out your Base tutorial
http://www.fhi.rcsed.ac.uk/rbeaumont/virtualclassroom/chap8/libreoffice_base.html
I was wondering if you would like to add a link to it from the TDF documentation wiki
http://wiki.documentfoundation.org/Documentation/Publications#LibreOffice_Base_Guide

Tom
