K -- The RHS form can be downloaded from
http://www.rhs.org.uk/plants/registration_orchids.asp . A paper copy would
be a nice courtesy, but the url would be enough for most folks. [And RHS
takes plastic, so there's no delay for checques to clear. Even with just
regular airmail postage, the RHS registration takes only 10-14 days, start
to finish.]

I hope your instructions won't stop there, but will go on to advise the
exhibitor what to do _after_ s/he gets the registration papers back from
RHS.

And I'm going to ask that we add the form for registering a hybrid along
with the instruction sheet. Why not?
