Help Me Collect a List of Contests that Drive Growth and Engagement (Information Bounty) - Paying 3 STEEM Per Qualified Response!

I would like to put together a list of contests that are being run which encourage new users to join, or encourage existing users to engage with the community by participating in the contest. I am willing to pay 3 STEEM per 'qualified contest'. The details on what qualifies for payment are listed below.

Examples:

• Photography Contests
• Art Contests
• This Post

Rules:

• Reply to this post with the info about the contest.
• The contest must be in the form of a post.
• The contest must be a way for users to earn STEEM or SBD by participating in some way.
• The contest must be one that users can still participate in. (Not one that is already over.)
• Repeat / ongoing contests are preferred. Just to be clear though, they will only be counted as one contest even if they occur multiple times.
• If there are duplicates, whoever posted the first link will get the award.
• The bounty is open until the payout of this post closes.
• All payouts will be made within 24 hours of the post closing.
• Users are allowed to post as many links as they want.
