Need a little help with removing "Powered by" text from footer area of wordpress theme

Stealing people's work is never the answer. I agree with NetStar, pay the upgrade. More information here:

If you like the theme, support the owners or leave the copyright message, it is the least you can do. If everyone steals, the developers would go out of business and you won't get better themes.
