Thanks to some feedback in the NWC Discord, the NWC Forums appearance has been adjusted to reduce confusion and highlight the active content.
The link in the top menu of this site takes you directly to the NWC Forums section within the NWN Campaigns site. However, after the registration process was complete, people were finding themselves redirected to the main NWN Campaigns page, which displayed a lot of other legacy / unused forums and didn't show the NWC forums until you scrolled down. The fix was moving the Neverwinter Connections section to the top, with the individual campaign forums beneath that.
Also a reminder that any group running a game on Neverwinter Connections can request their own campaign forum by following this link.
