I thought that was the whole idea behind such a forum, that is, to exchange ideas to help one another increase our knowledge and understanding of arrangers. I might know something about one area that you don't, and you might know something about another area that I don't. As a result we both learn something.
I'm a member of one forum that exists primarily for posting of arranger recordings the members have made. In your profile you choose which preference you want to display. "Positive Criticism Welcomed" "I Am Looking For Words Of Encouragement", or "Please Be Kind but Help Me".
Not a bad idea!
