EDIT: Never mind the question, just reread the first post.
There are loads of emblems you can get, but most require the staff members to see if you are worthy of receiving it.
Some others are given out if you take part in competitions or other events held on the forum.
Also, if you become a staff member or donate to the forum for supporter status, you get emblems for those as well. And there's also one you and your pair can get if you stay paired with them for a year.
