I'm from the UK and I've been a Pokémon fan since Gen 1.
I like knowing all the pointless details about the games. I edit fairly sporadically when I find something out or notice an error on the wiki.
The "jmvb" acronym doesn't really stand for anything, but inspired by my name on GateWorld.net (Jedi_Master_Bra'tac) - during my teenage years I spent a lot of time over there and was frequently referred to as "JMB" - I didn't want to use the same acronym on Bulba so I stuck a random v there.
I sometimes notice Pokétubers using Trivia/information I've added in their videos (ones like "top ten facts" which if you're familiar enough with Bulba you know are just copy/pasted from trivia lists here). Kinda cool but it irks me a bit that they make money off my investigations (which I do for fun/desire to know ins and outs). I added a lot of the Revelation Dance mechanics which subsequently ended up in a Verlis vid lol.
