Jeffrey, was your second post a reply to my first post? I wasn’t questioning your expertise in any way. My comment wasn’t even directed at you. I was asking for more detail from the original poster.
Yes, this is absolutely a place to ask and answer questions. Although my answer was from a different approach from yours, it in no way disparaged or discounted yours.
I often ask further questions when I post, because it helps me to be able to answer within the trainer’s scope as well as within my own.
