I was recently tasked to create a closed design community for a client, who wanted forum like functionality for users to create usernames to post relevant topics and other users can respond to them and assign users as moderators with privileges to delete or sticky posts.
Community X.
Connect with other creators, share ideas, give feedback and get the latest product updates.

Hi,
Great question you ask. Well this community forum was created on Editor X :) You can check out the Forums app from the app market to see if the feature set meets your clients needs. Please let us know if you have any questions about it.
