Code:
mob/var/list/ignoreing = new 

mob/verb/tell(mob/PC/M in world,msg as text)
    if(usr in M.ignoreing)  
        if(M == usr)
            M << "You told yourself, \"[msg]\"" 
        else
            M << "[usr] told you, \"[msg]\""
    else
        M <<"<b> [M] is ignoreing you!"



mob/verb/Ignore()
    set category = "Communication"
    var/whotoignore = input("Who do you want to ignore?","Type the name of the person you wish to ignore") as text|null
    if(whotoignore == null)
        return
    else
        if(whotoignore == key in world)
            usr.ignoreing.Add(whotoignore)
            usr<<"<b> \blue [whotoignore] is added to your ignore list!"
        else
            usr<<" <b> Sorry, [whotoignore] must be in the world to be ignored!"
mob/verb/Unignore() 
    set category = "Communication"
    var/whotounignore = input("Who do you want to take off your ignore list?") as text|null
    usr<< "[usr.ignoreing]"
    if(whotounignore == null)
        return
    else
        <b>usr.ignoreing.Cut(whotounignore)</b> //problem is here
        usr<<"<b> \blue [whotounignore] is now off of your ignore list!"


Problem description:
The ignore function works fine, but how do I get the whotounignore to subtract from the list? I've never understood how to subtract from a list. Can someone please explain?

list.Remove("textstring")
//or
list.Remove(object)
//or
list-="textstring"
//or
list-=object

Okay, thanks for that, I didn't know to use remove. I tried each of the examples, and they still don't fix the verb. Any idea why?

yes, because you're inputting something into the list as a 'key' and you're pulling it out as a text string. You want to pull it out as a 'key' as well.

Can you give me an example of what you mean?

var/list/bleh=list()


mob/Login()
   bleh.Add(src.key) //I've just added a KEY to the list.


mob/verb/test()
   bleh.Remove(src.key) // I've just removed a KEY fromt he list.
mob/verb/test2()
   bleh.Remove("[src.key]") // I've just attempted to remove the save value, but it didn't work.
   for(var/A in bleh)src<<A //As you can see, the key is still in there.

The key IS a text string. If you actually tested that code it would work fine.

So it does... well the fact remains that your problem is i fact what I said. You're removing a text string where as the object in the list is a client's key.

The code you just posted proves that that's not the case. Assuming the player spelled the key correctly when they choose to unignore a key, it would work. The problem is that you're depending on your players' good spelling to make it work, which is bad. Instead, the unignore verb should prompt the player to select a key from their list of ignored keys directly, like so:

var/whotounignore = input("Who do you want to take off your ignore list?") in usr.ignoreing

//and then to remove them from the list

usr.ignoreing.Remove(whotounignore)

I think the point of the verb is to use a text string.

For the ignore verb maybe, but it makes no sense in the UNignore verb. It would only invite problems.

    var/b=input(src,"Select a user below:","Ignore")as null|anything in a
    if(b==null)return
    for(var/mob/m in world)
        if(m.key==b)
            src.ignored+=m.key

mob/verb/Ignored()
    if(src.ignored.len<1){src<<"Nobody is ignored.";return}
    var/a=input(src,"Select a user below:","Unignore")as null|anything in src.ignored
    if(a==null)return
    src.ignored-=a

Try this, didn't have time to add notes, sorry. :/
