Greetings mageon,
If you have access to play the game, you should have access to post in the forums. If that is not happening, then the forums are likely not getting the message that you should have access to post in the Alpha Two forums.
You can try signing out of everything completely and close out all of your browser windows. Then open a new browser, sign in to the
Ashes of Creation website and check your
account inventory to make sure you see Alpha Two listed there.
Click on Forums at the top and Signin to the forums with the same account credentials. If you have access to Alpha Two, it should list that as a Role in your account profile.
If that still doesn't work, put in a
support ticket and we can look at your account.
