The only introduction of yours I see is the one above where you say nothing about your practices or how long you’re practising.
No, just once but you have to actually introduce yourself, and more specifically:
So you’re not practicing? You just know from an academic point of view?
Personally I don’t care to “categorize” anyone, we ask specific things from an introduction in order to avoid situations where one may introduce as a total newbie and suddenly starts giving advice to other newbies like they have years of experience or vice versa. Its our way to avoid trolls and know whether someone is larping or not.
