how about an idea where the GM hides somewhere on sapheal and ppl have to whisper him/her and guess where he/she is and the winner gets 50 mclay and 70 gold

There is an event very similar to this idea.

You can find the information for it Here, you can also find the times it runs Here.

Also, your signature is too big. Please follow the Signature Limits.

EDIT: The only problem I really see with your idea is that the GM will be flooded with whispers which may cause some people to miss out on winning since their whisper may be missed.
