There is no group, but you're expected to come online enough to participate in the Roleplay.
In the Four Clan RP, we're using the amazing Warriors Map provided by VitaniaKopa, as seen on Youtube. We're not claiming the map or anything, just inviting people to Roleplay there and support VitaniaKopa because it's normally so empty! =)
Please use proper warrior names unless you're a rogue. Put WindClan (WC), ShadowClan (SC), RiverClan (RC), or ThunderClan (TC) after your cat's name if you're going to Roleplay.
The map can be found here:
