Hello again and thank you very much for ansering my last questions.

Please tell me, how can i give an author of a topic the permission to suspend users from "his" topic?
I ask only for topics. not for Board-moderation. I dont want to give general Moderation-permissions.
Some people asked me about this option.
For example: "Bobby" opens a topic with his own theme. "Jimmy" comes and disses around in this topic. Bobby and his topic friends want to suspend Jimmy completely from his topic. Only from this topic.
I hope you understand what i mean, because, again, my english is not very well.
Can i give a TOPIC-Opener this special permission?
Thank you very much.
Daniel
