Aaaaand I'm done wiki-side. Phew !
I'll add some stuff about electricity when I'll have more experience with it but in the meantime I'll focus on minor edits, phrasing, grammar and such.
By the way I changed the Steam tutorial from the Squeezer/Coagulator to a more simple machine, the Automatic Hammer because it made more sense: making rubber for a HazMat (or an IC2 Generator with the previous recipe) should not be the first task when getting to Steam...and the Automatic Hammer is easy to make and only of use until the Crusher so it's perfect as tutorial material.
I'll don a burial for my old IC2 machines, illegitimately obtained through what seems to have been really dirty easy recipes.
Only friends and family are invited, I want to keep this small and private.
