Welcome.  One thing you can try, go to your main page, not private, but public
preview (can navigate there from the top left flydown menu under your
name). When you get to your public page, the left side top has some
links. One to revelife's home, then a flydown to navigate your site. If
that doesn't help then there's a third button that says edit theme.
It's a bit confusing, but it lets you add the modules you want. (That's
eventually where you go to add a custom module so you can add a music
player or a video, slideshow, whatever)

I added a bunch of stuff then realized I'd actually duplicated most
of what they'd already put on as defaults, but it's easy to delete a
module. You can drag and drop 'em too,to arrange your page the way you
want it. You can choose layout (columns, set up, etc..) in that same
editing window. Just don't forget to save it before you close it.

Then if you're feeling real daring you can go look at themes from
in there, too. They have a lot, but it's kind of tedious to paw through
them. Hope that's some help.  Ooops... sorry this was so long.  I tend to do that.   :-S
