I'll second Liz, Sandra. I'm sure everyone who visits this board realises that the vast majority of contributors are enthusiastic amateurs of all backgrounds who post in good faith with the intention of being helpful, especially if we've been helped ourselves. Any scrap of information can be a step to getting out of a 'hole'! When someone helps me I'm very glad and grateful, but of course I check it out myself or take with a pinch of salt if I can't. I hope other people do the same when I chip in.
