About the coding, everything you need as far as PS! source code goes is available here at Zarel's Github. You don't need permission to work on anything really the stance is that if you want it you can make it but whether it gets implemented in the official Pokemon Showdown site/server then it'll have to go through Zarel. But again, you don't need any permission to work on anything and good luck!Thanks for replying :)
I don't remember the moves exactly, but if I stumble across them again, i will let you guys know.
When i was a beginner, i really didn't know any commands, didn't know what mods where, i just wanted to put all of my favourite pokemon on the same team. I don't think that an intro link at the bottom next to replays would hurt experienced players, only help new players :P
Also, i would maybe like to try coding a mobile showdown app. I only have 24 hours of coding, but I'll let you guys know if I make any progress, and won't create anything without your guys' permission
