"With the best of intentions I offered to assist Sue when no one else including yourself had offered previously."
I don't have a problem with that. I wasn't as clear as I could have been before; as well as the concern I expressed (which was not my personal opinion but how it could be interpreted) sharing the information on the board where the request was made gets the information out for all to see.
Others can learn from what you share. There are always new people coming along who know nothing, and even those who are highly experienced can discover something new.
You might make an innocent mistake or assumption, and someone else may be able to pick this up and correct it - which wouldn't happen if you corresponded directly with the original poster.
There are a whole host of reasons for keeping the conversation on the board where it started, this is just some of it.
I didn't post before because I had nothing to share on the subject.
I'm the board admin, but that does not make me the world expert on the region nor is there any expectation that I have to answer every query.
Please keep sharing here, Alex. You know stuff that others don't (even if you don't think so) and can make a contribution that helps others. That's what the boards are for. :-)
