Dear Whimseywoman,
The question starter of this thread was posted on the third of the month. I responded to the poster at that time. You dug the question 18 days later to tell us that you have no idea what I am talking about. The poster did not follow up on the question for nearly three weeks since I posted my reply. This is an indication that the poster understood what I talked about. It is not important that you have an idea what I am talking about. The poster does. I understand you just registered in the forum today. If your comment is to help the poster, it is too late.
If you did not understand my directive to the poster and you would wish to understand, then seek knowledge by asking a question, you shall be answered. I will be glad to help, and if it is not me, many good will people here would be as helpful.
