Add a party system sometimes you meet people you dont want to just add on steam just play with them for the time being and with the party system you should make it so they have their own voice communication together in the party so they can switch channels from the server to the party and have a nice glow for the people in it so you can spot out your friends easier (idea from Garrys Mod Dark RP)
Heres an idea
