I just registered here and don't quite understand how to do my introduction or complete my profile. Any help?? The tutorial isn't real clear to me.

Well to post an introduction all you need to do is do the exact same thing you have done here but post in the introductions section. So, post an introduction in the Introductions forum and to complete your profile, click on My Controls, which is located near the top right of the page. From My Controls, click on Edit Profile Information which is found on the left hand pane of the screen. Now update your profile and then you done !

David.

You have been very successful in posting your introduction.
Welcome to BC!
