Hi all, I really appreciate the dedication and effort someone generously put into answering a question. i want neither to waste such a lovely people's time by saying irrelevant things nor to sound harsh or dry to them. It doesn't kind of feel right saying nothing when someone gives me a rather lengthly answer, unless it was the tacit agreement. So i'm facing questions whether or not to make a post, because i'm not sure which are the right/usual manners for this particular mail-list form of communication. My questions boils down to : how/when to provide feedback? If for example i ask a question and receive answers from three people. Should i always answer back ...commenting whether if it worked or not? ...only if it didn't solve my problem or if i had something useful for solving it to add? (like Stack Overflow) Should i answer back in a separate post to each of them or in a single post to all? Are one-line smalltalk comments alright here or should i avoid them? Any other advice on manners is also welcome. A written manifest would be nice :) Best, Laura
