Alternatively you can also vote for your favorite slogan by pressing the back button (the plus icon next to comments, posts, etc.).
If you're not sure what we mean by 'slogan', then check out this

A winner will be chosen from among the top voted comments by the Backed staff.
The contest will end one week from today at 12 Noon PST.
Eligibility:To be eligible you must create an account on Backed and provide a valid Bitcoin address (so we can send you Bitcoin if your slogan/entry is chosen). Only one account per person can be used for this bounty contest.

The bounty will be paid out in Bitcoin (0.25) after a winner is announced.
If you have any questions about the contest rules or requirements just leave a comment and I'll amend this post with answers.
Good Luck!
