@admins - so I've started making a point to regularly check Wiki activity and see what edits are being made. Anything obviously wrong (like spelling, grammar or just nonsense) I'll monitor and revert! As I learn more about the style (like someone added a 'Goofs' section) I'll get more pro-active with that.
I'm sure I'll get stuff wrong so please do tell me :) I hope it helps a little bit! Anything else I can do, I will.
