Thanks @Happy-Haze ! I have been trying very hard to solve my problems myself. I have finally comprehended that I have to look in the wiki for older items. In the beginning I was googling everything but once I bookmarked the forum I searched here for everything and sometimes came up short. But I have at least one question which will be coming. I canโt remember...
Speaking of, in Easter 2015 I think in the last location, there are a bunch of equations I have never found a use for. I can probably find a screenshot....
