Following on from my comments of earlier today, here is a competition from the Guardian with far more favourable terms and conditions. They offer a competition like this every month, and the prize is an entry-level DSLR from Nikon. For those interested, the relevant clause in the T&Cs relating to the licence granted is as follows:
By submitting an entry to the Competition, You give GNM permission for your entry to be published on guardian.co.uk and grant GNM a non-exclusive, royalty-free, worldwide licence to republish your Competition entry in electronic format and hard copy for purposes connected with the Competition
There it is: “for purposes connected with the Competition” – which looks like a good deal to me. The theme this month is macro photography.
