Show Tagline and Restore Accidentally Edited Footer in Wordpress Theme

Ok, today wanna be a geek has a new look! I've spend a lot of my time to edit this new look, and face a lot of problem when editing. The first problem is, I want to enable tagline in this new look, because when I use default template from Wordpress (twenty-ten), when I load the homepage, the site's tagline was shown. But after change to this new look, the result is -> no tagline! Ok, some templates don't show your site's tagline, but we can edit a little about your template so it can show your site's tagline in your browser!
