Vince,
you may not have known.. but there is an open vote just about every year on this topic and it always gets voted down basically because no one wants to be responsible for the extra work load it would create to add the 6&U's as I have continued to proclaim if some people would step up to the plate and say "Yes I will volunteer shoudl we add this" then maybe it would have a chance but that never happens. Most of the time people will say that they are willing to help but when it comes time to do it they are the first to back out and say they have other things to do.
