May I suggest a rule.

'By entering this competition series you agree to abide by the organisers decision outright'. [ or words to that effect.]

In other words you are God! If you say its Monday - then its Monday. I know they can challenge a decision at a cost of £5 but they might save up their pocket money!

I had a word with a couple of the club members last night and they have shown an interest. Mr Wilson may even dust off his old Gammo Centre to use that in the compt.
Once more details are finalised I will put a notice up at the club and collect some names (and monies. )
