There's nothing here to suggest that the OP's attitude or manners are anything other than humility and politeness. Quite wrong in my view to reduce the situation he described to 'dobbing in'. He's received some constructive suggestions, which have hopefully helped him come to a view of how to handle the situation. My earlier post talks about a level of CTAF communication, which I agree is very important. By the same token, a CTAF frequency is no place to have a full-on discussion, if that's what's required.
