The situation is I only want some people with high reputation could initialize a new post and other people could only reply to the post, is there any existed way to do it?
There may not be a way to automatically assign the privileges to people with a certain amount of reputation, but you can give one group the "Create Topics" and "Reply to Topics" privileges, and give the other group only the "Reply to Topics" privilege.
@leonrennz To expand on @PitaJ's reply, you can create a plugin to automatically add people to that "Create Topics" group once they reach the specified high reputation.
Thanks so much, that makes sense. @PitaJ , @pichalite
