Currently, every member can determine whether or not they want to enable / disable themselves from being displayed on the public Member Directory.
Space Owners can enable the public Member Directory by following these instructions:
1) Go to Settings > Front End Website
2) Enable the option labeled: Frontend Public Member Directory (see this setting highlighted in the screenshot below)
3) Click "Save" and now you'll see a Member Directory button on the navigation on the top right of your Front End website.
If you want a direct URL to your Member Directory, then it will have the following syntax (replace the spacename with your Space's name in the example URL below):
- EXAMPLE URL: https://coworkify.com/spacename/member-directory
