    Hi I have only just found your site and subscribed straight away for a year, I really appreciate the quality, presentation, delivery style and time taken to explain all the concepts and procedures, I have been looking for something as comprehensive as this for a while and up until now have not really found anything that suits my needs.
    Please continue as you are and I am particularly interested in updating junction tables with VBA and allowing the use of message boxes and input forms to guide the user up to the point of confirming data entry and or cancelling the operation before commiting those chages to the database. However, as I said I have only just found your site and still have lots to explore, once again many thanks for your time and committment,
    Chas
