[2008] Add item to list?

[want a pie]

Hey, I'm a new programmer in VB and I need some help
My problem is:
I have a small chat program, that enables users to chat to each other, but I need to store their usernames somehow. I know how to save settings, which is preferably where I want this to be saved to, but I don't know how to make it so that when the first person signs in, their name gets put at number 1, second person at number 2 etc. apart from having a long list of If statements that would take too long and be too slow =)

So thanks in advance if u can help me

P.S If you are one of those people that just says "do a search" so that you can just get up your post count, please don't. I have searched but don't exactly know what to look for, so if you could help me do that, it would be great

I take it this all will be done on the server side?
If you would add each users username to a List(Of String) as they sign in, you will automatically have them placed in the order they sign in.
If you're looking to use the Settings, create a setting of type System.Collections.Specialized.StringCollection and use it like any other collection.

here is what atheist is saying. it shows both.

        Dim Names As New List(Of String) 'this could be System.Collections.Specialized.StringCollection

        Names.Add("Tom")
        Names.Add("Martin")
        Names.Add("Mary")
        Names.Add("James")
        Names.Add("John")
        Names.Add("Lisa")
        Names.Add("Natalie")
        Names.Add("Emily")
        Names.Add("Nathan")
        My.Settings.storeNames = New System.Collections.Specialized.StringCollection
        My.Settings.storeNames.Add("Foo")
        My.Settings.storeNames.AddRange(Names.ToArray)
        Debug.WriteLine(My.Settings.storeNames.Item(0))
        Debug.WriteLine(My.Settings.storeNames.Item(1))
