I’d never heard of it, that is until I googled it just now. There is a fee to ‘enter’ so, not for me. I’d essentially be paying £30 to receive feedback I could get for free elsewhere. Cynic I am not. I don’t like the idea of entering comps. I’d rather take my chances with journals, but I’ve yet to try. It sounds like a very fun retirement pursuit though, best of luck with it.
