For those of you who would like to remove an entry from a contest, please contact our support desk team via the Live Chat button located in the footer page of the website. We will sort it out for you!
Only admin can delete entries to contests because once an entry is submitted to a contest its sent to our judging panel. Allowing members to randomly delete entries causes all sorts of pain as I'm sure you can imagine.
As mentioned, use the live chat button and confirm the URL of the entry you'd like deleted.
Depending on the contest, it's likely you can start creating a new entry right away, even before the other one is deleted.
