From personal experience I know this is a tough job as inflection, tempo, tone and intentional 'funny' sounding voices can not be heard via a keyboard. So a sarcastic remark or funny post can sometimes come off the wrong way. Being a Moderator, can mean rereading the post in question (several times in some cases) to try a interpret these things. It also means waiting for a response from the OP (post or PM) to further clarify what they meant. That is often the best time for a Mod to step in, at that specific time that the OP has clarified their post. None of this is easy and any Moderator who has been around for awhile, is still an active member of the board and is still liked/respected by the community deserves a 'hats off salute' for doing a great job of representing the community and themselves with professionalism.
