Porygon2 » Thirty for Thirty badge

Badges are given out to OzBargain users who have performed specific tasks. There are currently 4 levels of badges:

Gold	Outstanding achievement! These are the most difficult badges to get. Bearing a Gold Badge makes you a great contributing member of the OzBargain family.
Silver	Great achievement! These are awarded when you have done something useful on OzBargain.
Bronze	Good effort! If you have been on OzBargain long enough and have been actively participating in the community, sooner or later you will be awarded with Bronze badges.
Black	Ahem... This badge will be given to individuals & merchants with questionable behaviour. Might not be something that you would proudly pin on your shirt.
