Most communities don’t give their members enough opportunities to get more involved.
You can fix this.
Start a discussion thread calling for suggestions from members on resolutions or goals for the new year.
Should you try to release a product? Make a company change their ways? Organize an awareness campaign? Host an annual gathering?
Let members suggest which ideas they like. Create a poll and let members vote. Then create a separate forum category for members that would like to be involved in making it happen.
Failing that, just write a news post telling members what the community goals are for this year. Goals are good. Goals establish momentum. Momentum increases activity, encourages advocates and attracts newcomers.
