Thanks!
Honestly, It’s rare that people read the rules, or the pinned start here sticky so few know we would like an intro, and we have to ask every time… I had to be asked the day I was new too! 
We can’t mod though on who is a bona fide practitioner or not, that’s a subjective judgement that’s going to be questionable so we just ask for one from everyone.
But part of the reason for an intro, is because the professional mods we had that wrote the rules noticed that asking for an intro discourages those who are not here to join us in our seeking knowledge, but are maybe thinking of only trolling: it’s too much effort for those not actually interested in the forum as much as what entertainment they can get for free.
