I'm new to this forum! I need some pointers on how and where to post things here - I don't want to accidentally offend anybody. I know that this type of community generally has a "code of conduct", often unwritten, that new members usually violate by accident. Can anyone direct me to a good starting place that I can use to read up on expected behavior on the forum?

(edit) I have read the announcements for the boiler-plate rules. I'm looking for some of the unwritten code! ;-)
