Group moderators can create contests or challenges for their groups

The functionality now exists so that group moderators can launch writing contests or challenges for their groups. For now, the moderators will have to send me the details and I will upload it into the group. Once that happens, members of the group can enter the contest/challenge, just like the Strongest Start or the 7-Line poetry contest.

If a moderator wants to launch a contest, please include the following:

- Contest start and end date.
- Contest description
- Prize (doesn't have to be monetary and there doesn't even need to be a prize).
- Theme
- Any other contest requirements.

Thanks,
Sol
