No problem; WATMM is here for the finer details, (filtered through a mesh of passion and adolescent bickering). Google serves as a first front anti-ignorance gate; you might have easily established the veracity of PLUS via google, no trust required, then basked in the glory of your new found knowledge as you joined the rabble on WATMM in their praise/puzzlement/demands.
It's not as if that intermediary step takes all that much effort. Surely less time than it takes to field snarky responses from crodgity old farts like myself.
