Slogan Slingers is a website where businesses can go to find new slogans. You can sign up as a writer for free, and if your slogan is picked by the business, you win the prize amount for that contest (minus a small fee). The previous minimum prize amount was $200, which is a good amount for writers but was discouraging some businesses from utilizing the site. But the site administrators recently lowered the minimum amount to $50.
Hopefully the lower minimum will attract more contests for writers. There are currently two contests going on -- one for $100 and one for $150.
