Great question Serena. Yes, anyone can add a prize. If you are also a contestant, the worse that can happen is you win your own prize, and in that case maybe you’d say to give it to a winner of another category.
The Golden Panty Awards are a fun way to recognize our own. People might offer a special link or recognition on their site to the winner, offer to respond to their email from asshats, maybe the region where you live has something nice that a person in another part of the world wouldn’t normally find (a special candy bar, wine..whatever), maybe you make neat jewelry, etc. Things don’t need to be expensive or big, just something nice that a seller would appreciate. 😉
