Hello and welcome to Neuro Talk Richard, sorry for the reason you founds us, but am glad you did find us. this place is filled with many helpful and warm and funny people, dont hesitate to ask anything and follow the link and asking in there will give you more insight and if ya feel like goofing off, here is a thought, this is a link to the social chat forum, where we all tend to hide when the mailman delivers our medical bills

again welcome to Neuro TAlk aka NT, peace
