I can't reply to threads or post new ones and have confirmed with Smile and Nod that he can't either.
I don't remember where but I seem to remember this being a problem previously on other DM faction forums. There's a setting I think either on the PC end or the DM end for "Approval required" of forum posts. All your posts should still be there the setting just needs someone to flag it as approved.
I even made a new account and could make like three posts after gaining access but the issue spontaneously happened again. From what I can tell, a DM has to go into the new thread or the post and approve it before it can appear, which is obviously a hassle for all parties involved.
Must be because you're all enthralled, can't have thoughts of your own unless your masters approve it? Hah. Hope this gets fixed soon for you guys.
