Oh please. Don't be sorry.
It was a very good question. And you did not know where to look to find the answer.
The forum is the perfect place to get it resolved.
I think I will move this to the Frequently Asked Questions area of CSB.
It is a common issue that everyone should know.
But like you, many do not so I like to post it on several pages on the site.
I am glad you asked the question so it is now part of the forum too!
