Tips for running your group
Ultimately it is the Admins that decide what the rules are for their group, but if you have been made an admin of a Flickr group, here are some suggestions for keeping your group happy:
Admin Guidelines
If you are the administrator of a group, here are some pointers for creating a thriving community:
- Invite your friends and anyone you know who is interested in what you are interested in. Having group members is the first step in having a successful group!
- Visit the group frequently. Groups thrive with daily discussion, and with daily responses from other members of the community, in chat and on the discussion boards.
- Moderate, moderate, moderate! Successful groups are kept in check by good moderation. Tend that garden; pull the weeds, mow the lawn, prune the roses, etc. To help you moderate your group, you can enlist other members to become moderators. Moderators don’t have full administrative power, but they can help you moderate pool submissions, keep tabs on discussions, and weed out the people who don’t play by the rules.
