that's really not the way to look at it, the fact something or someone has already done something doesn't stop others from doing the same, but better or easier accessible or more flavour or less flavour...
if that was the approach then really nothing will go nowhere... Warren (and Melissa) has done something nothing stop me or you, tomorrow next week next year in 5 years time to do what they did,do but better or more innovative or different flavour!
Well done @Warren Melissa Go Riding i did something very similar prior to covid using WhatsApp and email, but more on the social outrides... it ran well for close to 2 years then attendance wittered down and my life got busier... haven't had the energy to get back into it again but i met some great people along the way who stay good riding mates to this day!
