The recently-launched Neverwinter Nights Workshop community site is dedicated to hosting guides on all aspects of NWN and NWN:EE gaming. The site owner, Orion, has been a long-time NWN gamer and has done a lot of work on various PC builds, among other things.
Regarding multiplayer and DM-led gaming, Orion found out about Neverwinter Connections and its guides and resources. After doing a lot of research, he conducted an extensive interview with Carlo on the subject, which goes over both the contemporary NWC site and the rich history behind the original one.
The interview, which includes a number of graphics from NWC and its community members, can be found here:
