As my esteemed colleague Mr Blank has just so eloquently answered the questions @BigRedX has, could I just point out...
The "in jokes" are only in jokes because those of us whom contributed in the beginning, had broadly the same sense of humour.
They are not meant to exclude anyone and if , as a newcomer, somebody wants them explaining we are more than happy to do so..
My alter ego of Dr Mondeaux for example (the one where I am probably responsible for hurting your brain... because of my ridiculous phonetic spelling ,meant to imitate Parker of Thunderbirds fame, using a Nottingham accent...sorry about that), came about because I was meeting @Teebs in real life to go to a gig in his area, and I jokingly said "don't worry I'm not going to be harvesting your organs."
I happily ignore just about everything else on Basschat because I got the information I was after shortly after joining, and I have no interest in the minute details of, ownership, playing, or the recording of bass, or any other instrument.
The DOI kept me sane during lockdown...I live alone ,have health issues and was getting more and more depressed...so I am grateful that @ped allows it to flourish.
I hope we don't bother the mainstream members too much!
