Threads Promoting your content
 

I've put a prefix of 'Threads' for this suggestion but this could easily apply to any user submitted content (groups, social group discussions, albums, album pictures, calendar events, threads, blogs)

It's similar to email to a friend, but more like Facebook in that you can share what you have posted with a friend or friends to something you have written via the pm/notifications system.

So basically I post a thread/pic/blog and then I can send it via the notifications system to friends that I specify.

This could boost activity and alert members to content that they are more likely to have some interest in.
