Imagine you are a new member of this forum.
They don't know any of the forum members and have no idea if they are fine upstanding folk or downright rotters.
I suspect very few new members will be joining the forum in the expectation of someone offering to come around and offer practical assistance, indeed they may well be taken aback by such an offer from a compete stranger.
I know the motivation for offering such help is with the best intentions, but I think it is fair to allow new forum members to find their feet before prompting them to 'reveal' their location.
Those who are confident to say where they are, often do so in the first few posts, those who aren't at first will often share the information when they have settled in.
