I have just spoken to the organiser, whose name (and email) are on the entry form.
june.english@btinternet.com
You Merkins can send entries as
unidentified (Word) attachments, with your details in the body of an email, to that address. Please put Torriano Competition in the subject line and quote your PayPal transaction number.
Or you can send them by post - quoting the Paypal number in your covering "letter". Entries postmarked by the closing date will be accepted, even if they arrive a day or two after.
This has all been set up in a hurry, so I apologise if it looks like a dog's breakfast.
ps. The named judge will read ALL entries.
