[Suggestion] Allow members to edit their threads in Journeys section

[cerebration]

I like reading a lot of journeys and I’m sure I’m not alone.

But some journeys get huge. They get a lot of replies and can get messy.

My suggestion is to allow members to edit the first post of the journey. That way, it is very easy to just edit the thread, draw a line and add the update at the bottom.

If implemented and used properly, reading a journey from the beginning to the end will flow a lot smoother.
