Thanks for the welcome. Never used a forum before, "newbie". Hope not to screw up too much. Teaching an old man new tricks can be difficult.
Pretty hard to screw up the forum. One hint though--when responding to individual posters, you may want to address them by name. You have several responses in a row and we're not sure who you're talking to. An even better option is to use the quote button instead of the reply button. That way the post you're replying to will show up in your response--like I did.
