Sorting portlets

Hi Everybody
I have a problem with sorting topics in portlets.
I want to sort them descending.
Is there ant way to do that?

Could you please provide a more complete explanation and screenshots to describe what you currently have and what you would like to achieve?

Thanks for responding.

You have to change that in each Collection's Edit view (search for the "Sort on" field). Have a look at:
