Yes, you'll need to complete your probation before being allowed to post in RWI.

At the moment there are no other restrictions in place for probation accounts.

All new accounts will be subject to probation status. You are allowed a maximum of 3 posts within a 12 hour period.

Probation accounts are not allowed to edit posts, and are also subject a a number of other restrictions.

You will be automatically promoted out of probation once you have made at least 50 posts anywhere in the forums (not to be confused with your post count).
