I also believe strings are over and misused in modern programming.

I don't like huge if/else if/else if/else if/else if/else if blocks (and then there is the O(n) time complexity of it..)

have a look at the GetOrAddTabPage function, it will give you an idea about how you can do that.

private TabPage GetOrAddTabPage(string TabName, TabControl Control)

        if (item.Text == TabName) return item;

// Here you come to the point where the user whose name is in the
// "UserName" variable received a message - you must get the
// corresponding tab or create a new one if it doesn't exist.
// "MyTabControl" is the tab control you created on your form.

TabPage UserPage = GetOrAddTabPage(UserName, MyTabControl);

// Now "UserPage" contains the user's tab page, and you can use it.
