Ummm yes, it is. I don't recall saying it was not.
However since you were speaking directly to me (an assumption quite understandable since you quoted my post and then left a response directly under it) - I was speaking back to you to let you know I didn't know what you were talking about and that I was not seeking clarification of your response, such clarification was unnecessary for me.
However, if you were not responding directly to my post and quoted it in error .... and are in fact addressing a wider audience ... then by all means expand upon your post should you so wish.
