In order to post new messages or respond to posts, you must first write a post that will be approved (or not, as we get a lot of SPAM) by the administrator. If it is legitimate, you will be approved either as a subscriber or a contributor. As a contributor, you will be able to upload family photos and write articles.
You should also sign up as a user using the log-in under META at the bottom of the page. Please use a password containing at least ten upper and lowercase letters, numbers, and characters. You would not believe how many hackings are attempted daily.
