I'm certainly one of the offenders here, maybe the main or even the only one. Sorry about that.
In all probability I have used the wrong 'quiet' instead of the correct 'quite' all my lifetime (I really thought it was the same word with different meanings). So thank you for the little lesson I should have learned a few decades ago. I'd really appreciate if you would correct the many omissions of my english teachers in the future, as soon as you see that I make the same error several times (I'm a bit prone to typos; and my ability to write English is a bit dependent on my daily form). I don't have a problem with being corrected as this is the only way to learn something (and I'm still not that much used to write English. So my grammar and my orthography are a far way from being perfect). I already ask for forgiveness if I'll use 'quiet' in the wrong sense out of bad habit and because of a memory that meanwhile is working on a lottery principle.
But I would prefer if you'd do that directly addressed to me or maybe even in a private message. Not because I'm ashamed of my orthographical wrongdoings but because I see a little problem in stuff like this. Don't get me wrong, please. I see the problem, even more so in German. That language is utterly deteriorating as I see it daily in newspapers (and I'm not talking about the equivalents of the 'kronenzeitung' but 'serious' papers), comments, letters, advertising and whatever. People not only lose the ability to express themselves but that of understanding, too. So many perfectly German words they don't get anymore. Or they happily read over things like 'keinesfalls', understanding quiet the opposite of what's meant. The really bad thing is, that's happening at university level, too (I have seen horrible things done to this poor almost defenseless language from people who really should know better).
But in the case of international forums like this one here I'd make an exception in any language. Because for people who don't use English very often and know fairly well that they are not that good at it, it's sometimes quite difficult to overcome their inhibitions. They are self-conscious and even ashamed of the simple fact that they don't handle the foreign language very well. I actually know some people who don't ask questions in a forum (or to the support) if they have to do that in English. Not because they are not able to but they don't want to come over as stupid or uneducated. So if we talk too much about spelling and grammar here, some people might be discouraged in writing here.
On the other side, It's only my opinion, and I may be utterly wrong.
(By the way, I myself have stopped long ago worrying about what people think of me because of what and who I am and what I can do or not. I don't try to disguise my short comings or to act as if I was somebody else just to be liked. I honestly don't care. But I try to write half way correct English out of respect for those who read the postings. So, yes, I like to learn).
