Other moderators are fallible, but I am always right.
Except when I am wrong.
Seriously though, Raymott is right. One of the good things about this forum is that none of us claims that we have the absolutely correct answer. Indeed, be very suspicious of people who claim that they do. With several varieties of English: American, Australian, British (English, Irish, Scottish, Welsh), Canadian, New Zealand), to name but some of the main ones, and a range of contexts and registers, it is often very difficult to state that one answer is the only correct one possible. People who visit this forum regularly soon get to know members who generally give reliable answers. If one of those gives an answer which is 'liked' by several others known to be reliable, then you can be fairly sure that you can accept the answer as being sound.
If someone gives an incorrect answer (and even moderators do sometimes, as Raymott noted) the you can be sure that other people will soon chip in and set matters right.
