Here, getting badges seems hard, but all you need to do is check some of the badges you can earn.
At your profile, you'll see a bar showing your rank in the wiki, (SM64BF) and below there are badges you can earn. for example:
CLAIMING THAT LUIGI IS HOMOPHILE
Post a message at someone else page. (0/1)
