Following are the requirements:
1) You need to attend mod classes regularly.
2) If you miss a single class, then you may end up missing chance to be a mod.
3) Appear for mod examinations wherein the likes of BB and Wiz would be invigilators.
4) Once you qualify the exam, start a beer giveaway, wherein every member of the forum gets one can of beer bottle.
5) Last but definitely the most important requirement is that you got to stop asking stupid questions. ( There's negative marking for that). Don't take these requirements lightly and buy an e-book " How to be a BHW Moderator?" in order to prepare for the test. All the best.
