Hi there -
While you are viewing your profile, you can click the "Edit" at the top of the "About Me" box/widget. This will bring up a screen with your basic info on it, and you can edit it there. Be sure to click Save at the bottom right when you are finished editing.
To see all your posts, just under About Me on your profile, you will see the Posts box/widget. You will find your 3 most recent posts there, and when you have more than 3, you can click on "See All" to find all your posts.
I know you are anxious for answers, but it can take some time for our experts to answer. Please don't hesitate to post in our member forums - we have some really knowledgeable members. Our forum list is here -
