What are some good Howrse forum competitions?

I like to host writing competitions. Another good forum game is TPBM, or The Person Below Me. Example:

1: TPBM gets a foal!

2: Claim!

TPBM gets a Black Orchid!

3: Claim!

TPBM gets a MK saddle!

And so on. Also, a popular game is Rate The Avatar Above You. This is where you rate the avatar of the person above you on a one through ten scale.

Hope I helped!
