ajp153....you may not be aware that you can thank all the nice people who take the trouble to answer your questions by clicking on the 'post an answer' tab, and expressing your gratitude as if you were answering your own question.
Alternatively (or as well) you can award stars, which does at least show people that you've seen their efforts or your behalf.
Try it sometime!
kettledrum Kayakamina said a few weeks ago that he was not going to reply to this person again as they ask for most of the you crossword and never thank him, so I think this person must surely know how to say thanks by now, they are just ignorant but there will always be someone to answer their questions
