The Green Button
From Mario Fan Games Galaxy Wiki
The Green Button is a button that can be pressed by ordinary MFGGers when a "disaster" strikes. It will fix the topics_view table and sessions table when pressed, thus ending problems with blank screens after navigating the forums. It will not fix anything else (such as MySql errors) however, and will do nothing if clicked when no errors are present. It was created by Retriever II on the 9th March 2007. However, with the recent MySQL upgrade, the tables seem to be much less prone to breaking
It has also been rumoured that badges may be awarded for the use of it.
