how to unpin or remove announcement on topics

Hello I'm really stuck here, I pinned every topic and cannot figure out how to unpin the topics of the members. Now when someone posts a topic it is not viewable at the top, as the pinned topics overrule the most recent post. Can you please help me unpin or unsticky and or un announce a topic?

Many Blessings

hello

edit the thread scroll down and uncheck the pinned option

You can also click the moderate link below the topic list, check the ones you want to unpin, and click the normal button.
