My favourite reference is Eric S Raymond's "How To Ask Smart Questions".��
Now actually its a friendlier community here that the ones referred to in that reference, but it provides some good philosophies to adhere to.
Reporting back success as well a failure is really good practice, since it is gratifying to know it was worth the time to provide advice, and also the next person wanting to do same thing will find this in their web search.
Where the histories start getting long, trim them to just the parts you are referring to. ��
I vary whether I respond to separate posts or as a single post.�� Using separate posts you should trim history more. ��"Perhaps" I use separate posts in the middle of discussion and a single compiled post as a final summary - but really there is a lot of latitude here.
and btw, I think you're ahead of the game asking as you did.
