1) Student must post discussions or replies means: a student must either start a topic or reply to somebody else's .
2) Student must create discussions - means a student must start a discussion topic themselves
3) Student must post replies means - a student only needs to reply to a discussion someone else has started.
So (1) is an either/or whereas for (2) and (3) they do one specific action chosen by you.
Please see Forum FAQ #12 'How can I close/archive a forum?' for how to make a whole forum read-only, if that helps - but not separate individual threads.
