Welcome John to our Stamp Community Family. Best place to start is using our
search engine to find whatever topic you are interested. As far as posting, talk about something you are collecting, ask questions, offer help to someone's questions, post some stamp news no one has yet posted about a stamp. It takes a little while but you can have lots of fun and learn more about stamps and meet some friends.
Just go back a few weeks and read what others are saying and you will get the general idea.
