Hi Peter and welcome to RAD my friend 
As many have said I can assure you there are no cliques,
only members who have met up and made proper friends on the various 
rides and of course MK , hence the natural progression to use real names .
My first meeting with other RAD members was at the BMX Worlds in cologne 
back in 2012 , I was a relative newbie but just jumped in at the deep end and got 
to make genuine friends with peeps on here which still results in the same group of lads 
going on yearly holidays ever since then .
Just join in as much as poss and try and get yourself on a few rides and in no time at all 
you'll have made great friends and will be on first name terms with many others 
You are exactly what the forum needs to be honest , so get stuck in and enjoy your self 
Much love Mike ( Benno ) 👍🏼
