Since the game has no way to properly advertise for Global and Cross-Server parties, I have developed a system for Dungeons, Personal Story Instances, WvW Groups, Tournament Groups, Etc.
We all know that you are allowed to join multiple guilds and represent guilds to gain access to their guild chat. Since we have no “Global Chat,” I have made the Guild called “Party Finder(LFG).” The purpose is to represent the guild and simply ask for group that wants to do Arah, CoF, HotW, Etc., you will then assemble your group, run the instance and then go back to representing your group.
Since this is no actual guild, you may even use this as a recruiting source to find full fledged members.
If interested, please put your name in your reply and you will be sent an invite. Please note that the guild is new and will need some time to fully take off.
