Until when can I choose a winning entry?
When starting a contest, you can set your contest to run for 3 to 30 days.
You can pick a winner at any time while the contest is open, until 30 days after the contest ends. For the screenshot example above, if you run your contest for 7 days, you have a total of 37 days to pick a winner.
Once a winner is selected, you can also buy other entries (runner-up winners). Awarding multiple winners is also possible.
If you fail to pick a winner 30 days after the contest ends, the prize money will be automatically distributed among qualified freelancers (usually freelancers whose entries received the highest ratings on the contest).
