They offer free blog background for blogspot users without deleting your widgets. All you need to do to make it running is-- you must set your template first to Minima, add a widget and copy the html code of the background. My sister who's new in blogging discovered this and I must say, she's a fast learner. You can check her blog here and see what she did to make it more appealing. :)

Well, you can also see that I've changed my background but did not use minima...see the result? nah..it's okay with me..I think I like it. I still want a 3 column template eh.
