I like the explanations and arguments given, and I will have a look at the proposals and if I agree, as I'm sure I will, then my answer is given.
But why, I wonder does Orchidwiz not know about this, or the RHS Register ( although in the latter case it may well do , it is simply that the offered searvh engine on the RHS site is rather clunky and maybe a bit unreliable) . And perhaps Orchidwiz primarily relies on that ? I shall ask Alex.
