There needs to be a one-click option to check and see if all of the names you have entered still have their .com’s available. This can help in multiple ways
1] Check whether all entered names have .com’s in one go and tweak names without .com’s
2] To know whether the contest holder has registered any of the names/domains (Or multiple ones) while the contest is ongoing or has a winner declared.
3] Go back to an old participated contest and check for still unregistered .com’s
