TC's forums are at https://tarnished-coast.com/forum/ (also has links to their discord and teamspeak) for those looking for a group/guild. I transferred off TC half a year ago, so I'm not sure what's there anymore.
I am an incorrigible WvW player, personally, and am known to inflict WvW adventures upon my RP guild not infrequently (we do WvW guild missions, usually). Feel free to look us up in game! All the requisite contact information should be in my signature.
