There's rightly been plenty of interest in this thread because, after Keith "Boss", the moderators are the most important members of the forum I'm sure the three "youngest" moderators (Arthur, Penny and Rayna) would wish me also to acknowledge the debt of gratitude we ordinary members owe to the established moderators. They have individual expertise, balanced by good humour, patience in repeating advice to those who can't search for it, and (where necessary) the ability to censor or ban inappropriate contributors
Thanks Alan!
Welcome back
Good humour and patience are best tools to moderate.
