I’m not sure what you refer to exactly, but most people use the addon “total rp 3”. It has a handy map scan.
WELL… You either just walk into their group and start talking OR you start to look for singular people sitting somewhere. An rp guild might work for you as well.
Unfortunately that is what MAAAAAAAAANY roleplayers won’t react to. They might /wave back or ask what’s up IC, but from there on you have to continue the conversation.
Usually done in guilds, your guild is (atleast the one displayed in the forums) not a roleplay guild.
Even if you do, we all started somewhere.
DO IT.
Also this might come in handy.
