My friend and I both play Knight-Errant Paladins of the Silver hand! They recently joined a tight knit guild of Do-Good Vigilantes (of all types) to continue their story! However, the guild, while we really enjoy it - is a little low activity with one event a week and little RP in between.
We’re looking for an RP focused community - not a guild - to join up so that we have some other RPs in between our events and to get involved with some other folks and just expand our group of people we RP with regularly! They’re interested in Traveling for a bit for some personal questing and tend to hang out between Gilneas and Quel’thelas. (With their little Guild’s village being placed in the mountains between Quel’thelas and the Plaguelands.)
If anyone knows of any RP communities that offer a swing of different events and a friendly community of RPers that might fit our two Pallies - please comment so I can look into them! 
I am, sadly, not able to assist with this - but I am posting for similar reasons, as I’ve recently finished leveling my NElf Sentinel, and I’m rather interested in exploring some of the communities on MG-A, as a WRA-H player!
Hi Hi! The Society Circle (TSC) home is based on Moon Guard but caters to both to Moon Guard-US and its sister server Wyrmrest Accord-US.
IC, TSC is a networking club that welcomes people from all walks of life in Azeroth to connect and build rapport through business and community outreach.
OOC, The Society Circle is a Discord Community where players, roleplayers, friends, and digital artists come together to celebrate WoW, through the creation of stories, artwork, and the everyday friendship/support we build along the way.
Additionally, we offer a realm wide event calendar to help promote RP events hosted by players, guilds and communities, we publish a monthly IC newspaper called Azeroth Times, we provide player housing on both the Alliance and Horde, and host our own community events throughout the year.
Feel free to check us out at Discord’s /CSXxubYcTb
