Server Administration: ~8. I've run multiple (Don't ask.) servers over the last year, and my current one is running Tekkit.
Game Skill Level: Probably ~5. I know the basics of all/most of the mods. I've really gotten into IC2 and LUA in CC.
I otherwise know nothing about the bluetricity part of redpower, and just how to transfer things through pipes in BC. :l
I don't know enough about the other mods to remember them so I can mention what I know about them. lol.
