Most of the people here don't get paid for replying to posts. They give their time, their expertise, experience and effort for free. If you have been helped by a reply then at least tick 'like' to show your appreciation.
Some time ago I sent a comprehensive pm which took me some effort, as a reply to somebody who requested sources to buy meds. I never got an answer, not a thank you, nothing. It's put me off answering this kind of question again. I'm not working for the National Archives for Thyroid Treatment. I'm not an AI Public Information bot. I've had other similar experiences when answering queries which have been likewise unrewarding. I accept that it would be no great loss to the board if I stopped contributing but there are others, stars in my opinion, who regularly reply. I look forward to their input and I don't want to lose them because posters can't be bothered to even acknowledge the help that they have received.
