That's too bad. I would really need history tracking for Resource description.
Is there no way to embed the content of a forum post in a Resource Overview tab?
That would do the trick since forum posts have history.
Looking at the database schema it seems like resource updates are being preserved.
So that would be one way to have some sort of description history.
Just create a resource update instead of simply editing the description.
I have yet to try it myself. I'm not sure if the application let you access older resource versions in a similar way that you can access a post history.
