Detecting if a user is in a channel.

I want to know how to tell if a user is in a certain channel that is being removed, so the removal gets cancelled until nobody is in that channel. Here is a snippet that I need to have changed:
var/rnc = pick("red", "orange", "yellow", "green", "teal", "cyan", "blue", "indigo", "violet")
var/global/list/stations = list("  Main Lobby","Newbie Central","Recruitment Center","Designing Philosophy","Advertising","Ub3r Land")
var/sound
mob/var/sta = "Main Lobby"
var/susrs

mob/verb
    delete_channel()
        set hidden = 1
        set name = "delchann"
        src.sta = input("What room do you wish to remove?","Delete Room") in stations
        if(sta == "  Main Lobby" || sta == "Newbie Central" || sta == "Recruitment Center" || sta == "Design Philosophy" || sta == "Advertising" || sta == "Ub3r Land")
            if(src.sta && stations)
                usr << "You cannot delete this channel because you or someone is in it."
            usr << "You cannot delete this channel."    
        else    
            stations -= sta
            world << "Channel [sta] has been removed."


    join()
        set hidden = 1
        set name = "join"
        set category = null
        src.sta = input("What room do you wish to join?","Join Room") in stations
        src << "<font color=[rnc]>You connect to <b>[src.sta]</b></font>"

Make associative multi-dimensional lists. Like so:
var/list/Channels=list("Main Lobby"=list(),"Newbie Central"=list())


Then, to add to those lists, just do this:

Channels["Main Lobby"]+=new/mob


And, to see all who's in those channels, do this:

for(var/X in Channels)
    src<<"[X]:"
    for(var/People in Channels[X])
        src<<"[People]"


And, to "delete" channels, do this:

var/list/Temporary=list()
Temporary.Add(Channels["Main Lobby"])
Channels.Remove("Main Lobby",null)
Channels[1]+=Temporary
del(Temporary)
