We've just added a set of tooltips that introduce a new user to Weebly. It's a new user introduction of sorts that steps through adding an element, changing your site design, adding a page, and publishing. It also points out helpful tips, like what to do with the two column element when you drag it on.
If you already have an account, you won't see the tooltips, as it would most likely be annoying. If you want to check them out though, clicking on "Try Live Demo!" on the homepage is the easiest way to do that.
