I've created an extended family site on tribe to replace our Facebook Group. I'd like to bring over photos and documents both to trib.

Allow us to reorder topics so that they appear in the order we want in both the the navigation menu and the all topics view.   We can then promote the topics we want to drive more conversation to. 

Hi Elaina, 

Thanks for posting your question! 

Currently, there is no way to lock a reply to a discussion post. Here are some other options: 

• Archive the discussion: to make it less visible. Archived content will display in search results but will be removed from home feed, topic feed, group feed, or user feed. Learn how to archive a post here.11
• Limit access to Discussion Content-Type: Tribe has 4 content types5. You as admin can decide which one should be enabled/disabled. You can also define who should be able to post that type of content (Admin, Moderator, Member). This way, you can define only admins to be able to share a discussion. However, as soon as the admin creates a discussion, regular users still can reply to that post.

I hope this helps! Let me know if you have any additional questions.
