Where do you go to accept or reject answers on these forums?
In the thread itself for the specific post. The thread itself has a “Discussion” or “Question & Answer” status. You determine the type of thread you’re starting when you create it
When you view the thread, there should be a set of buttons (yes/no) on every post that is added to the thread.
That only happens if you used the “Ask a Question” option when you started the thread.
