Actually that is there also, but only on the main part of the site, not the message board. If you see someone online on the left, and click on their name, it should bring up their info. Problem is, nobody ever fills in their information.
When you log into the site with your username and password, one of the options should be, edit my info, this is where the info needs to be placed. You can also reach this by clicking on My Account on the left top part of the menu.
