could it be posible to allow the change of the description? it would be usefull if:

1) a user gives a bad title/description, it could at least fix the description
2) in a topic like the "MAREO 2.x discussion topic", i could update the description with for example "Last Version 2.1.1"

I think the problem is with the thread approach. It's not possible that somewhere within the same thread the thread discussions could split in several (or one new) direction and this be easily reflected with the Invision's approach. Correct me if this is actually possible.

I could have used this feature two days ago. *cough*

Hmm, interesting. I figured how you can do something like what I proposed. When you click on "Outline" instead of "Standard" at the top of the thread (right above Track this topic | Email this topic | Print this topic) then you can see a threaded view rather than a flat view. There you can see what replies are made to which individual posts etc.
