How can I achieve a topics page like this? Is there an Addon?

[leonhardtmm]

Hi, I am looking for an Add-on that helps me create a page like this:

Alle Themen

If I choose a topic on that page (Example „Abenteuer“) I land on a page like this:

abenteuer

abenteuer

www.planet-liebe.com

On this page the user can see who posted anything for the topic „Abenteuer“

Is there an add-on you can recommend?

Thanks in advance
Mario
