Hi Derek http://www.workerthread.com  brought this to my attention.  So I thought I would give it a mention it is the website of the UK Access User Group http://www.ukaug.co.uk/.  They do have some information on SQL Express on the site.  I have been asked to present a session at an event for them later in the year.  I will give you more details nearer the time.  The session will probably be interoperability with SQL Server and Access. 

There is a regional meeting on Wednesday 20th Sept in Cambridge see the link to the site above.
