I'm torn on Aluminum/Aluminium - the British chemist that identified it named it "Aluminum", along the same linguistic lines as "Platinum", "Molybdenum" etc., but the international chemistry governing body changed it to "Aluminium". By habit I use the international name, but I have no objection to the original British name that the Americans still use.
Since 1993 Aluminum and Aluminium are accepted. So you can call it however you want. But since it is followed by Gallium, Indium and Thallium it makes more sense to call it Aluminium, since Gallum, Indum and Thallum sounds kinda strange.
And well I use the time until the next pack comes out to test some of the newer mods. The 1.5.2 Pack and propably even more so the 1.6 pack will contain some new mods which i want to test before, so I can decide whether I want to play with them or not.
