Pat,

Obviously you're the only person to reply, but your tips are very appreciated.

I hadn't thought of Yahoo groups or Google groups. It may be that a Yahoo group is a little less susceptible to data mining or identity theft threats than Facebook, My Space etc. I notice that Yahoo groups have the option of password protection which may offer some advantadges over non password protected groups. I am too much of a cyber luddite to know for sure but there you go.

Cheers and a sincere thanks for your assistance, Pat.
