Again, welcome to the Board. And your command of the English Language is just fine. Only thing that could confuse you is here in the US "we" speak "American," which is a dialect of English. But, that's what makes the language the choice of world commerce. It's one big sponge; see a word, like the word and it can be in common usage in North America in a couple of weeks.
Think I'm kidding? Stick around teenagers for a couple of weeks and you'll find out just how out of date you are at age 59. Concerned about correct spelling; no need to fret, use the spell checker before you post. (I'm appalled at what it catches on me)
