OK, First off Dave, welcome to the Mudcat. As for tips on custom or protocol, just simply use the "Golden Rule", Do onto others as you would have them do onto you. I myself am fairly new around here, about 6 months or so, and it didn't take me long to learn that one is made welcome here as a matter of course. Realize that everybody, and this is a worldwide diverse group, has an opinion on any subject and it may not be the same as yours. They will all read your opinion and then offer a counterpoint, or agree with you. It is a very tightknit community, but a loose enough weave that there is always room for one more! You have no doubt been following the Catspaw's dillema threads. Most of us ahve never met him, except here in the cyber village, yet we all felt like it was one of our own family that was in the hospital, and we all rejoiced with each piece of good news we heard! I can't explain it, neither can a lot of other folks, save to say we are a group with a common bond (music), a common love of humankind, and a strong respect for each other. So, welcome and enjoy the group!
