If you want to customize how the system displays usernames in the administration interface, modify the **GetFormattedUsername** method in **\~/AppCode/CMS/Functions.cs**.

## Example

Usernames are displayed in the _ ()_ (e.g. _Abigail Woodwarth (Abi)_) format in some parts of the system, for example when editing documents in the Pages application on the **Properties -> General** tab.

The following code example shows how to modify the method to get usernames in format _ \[]_ (e.g. _Abi \[Abigail Woodwarth]_):

```csharp

using CMS.Membership;
using CMS.Helpers;

...

public static string GetFormattedUserName(string username, string fullname, bool isLiveSite)
{
    username = UserInfoProvider.TrimSitePrefix(username);

    if (!String.IsNullOrEmpty(DataHelper.GetNotEmpty(fullname, "").Trim()))
    {
        return String.Format("{1} [{0}]", fullname, username);
    }
    else
    {
        return username;
    }
}

```
