Can we suggest making a contest with a specific topic? for example, Earth's day, or something to do with "Green" stuff. Answered

You can ask the staff such as randofo, scoochmaroo, fungus amungus or ewilhelm. Their have been contests of that sort before, such as the Tap'd NY, Keep the Bottle Contest, and there are bound to be more, if you and others ask then chances are more will be made.
