I see a few problems. Most specifically using usr.
mob
     Clan
          verb
               Recruit()
                    var/list/peoples
                    var/lotsofem = 0
                    for(var/mob/M in world)
                         if(M.client && !M.Clan) //Kill two birds with one stone
                              peoples += M
                              lotsofem++
                    if(!peoples | !lotsofem) return //Don't do anything if there's no one to recruit.
                    var/mob/R = input("Who would you like to ask to join your clan?","Recruit") as null|anything in peoples //Gives them the option to cancel.
                    if(!R) return //If they hit cancel, stop.
                    if(alert(R,"Would you like to join [src]'s clan, [src.Clan]?","Join Clan","Yes","No") == "Yes") //If they say yes to the invitation
                         R.Clan = src.Clan //Assign their clan.
                         for(var/mob/M in world)
                              if(M.Clan = src.Clan)
                                   M << "[R] has joined [src.Clan]!"

It's a verb; usr is safe there.
