People have been answering my questions and I would like to thank them. Is there a way to reply to the posters?

Hi, jburn83468!

You could thank them on the threads that you started. If you wanted it to be really personal, then you could send them a private message. Although, I'm not sure that you've posted enough to be able to send a private message.

Thanks!
