#1 The Beginning

I just started this, and already I am frustrated.  "Help" says that to assign this to a community, I should select the "down arrow" next to "Community", and go down the list to...etc.  The only "Community" I can find anywhere on my screen doesn't have a "down arrow"!  Sob.  Also, when I click on the "Edit" button under "About Me", nothing happens.  Excuse me while I go beat my head against a wall........
