My idea is to get something like 100 toons into the upper necropolis, and have a huge gathering in front of the shield and tome vendors. A few disco balls cast, and have everyone /dance or /dance2. Take a few screenshots of the party. Maybe do a couple of /wave pictures and some /taunt pictures without the disco.
Then have everyone submit their various pictures to Turbine for the screenshot of the week. Caption ideas:
/dance or /dance2: Players on Khyber party in the Upper Necropolis like it's their last day alive.
/wave: Players gather to send a greeting from beyond the grave: "Hello!"
/taunt: Players prepare for update 23's Epic Necropolis by taunting the Black Abbot.
The beauty of the idea is that if it gets picked as the winner, we're practically rubbing the renown sploit in their face! "Oh look, these people were all hanging out there. It must have been for the picture only, purely innocent motives. Let's give them a bunch of Turbine points as a reward!"
