I am very grateful to you for your detailed answer. Though it is usual for dialogue in the Internet to not expect the answer, nevertheless it is difficult to get used to this.
Dialogue on the international sites has the specificity. I am not long ago in TL and TN, - and it was interesting: a lot of participants from the Arabian countries always thank each comment, - that is, there are special rules of dialogue.
I think, to hear words of approval is very important, especially for beginning participants and not so skilled photographers (it is about me too).
So, Bob, I thank you very much!
