My thanks to all who contributed. A few lessons from this: (a) Revisit and read the XARA homepage. There are some good readymade solutions in the module store for a variety of needs. (b) use the search site option (which I did not at first) it gave me all the answers. (c) I tried out site updater (could not find the tial option so I bought a months subscription). It works but is rather basic. Would help if you could create passwords for clients independently. (d) Read the replies to your original query - they can be quite funny but mostly helpful.
