The role of GetUserDisplayName is helping you get user's display name based on the user's UniqueName.
Before you get started, you need to understand the 'UniqueName' in CuteChat. In CuteChat, UniqueName means the unique data of your user. Depending on how you implement the user system, in some systems, the best unique data is the user ID; in some system, every user have a unique account name; some systems like MSN, the unique data is the user email. It could be string(username, email), integer(user ID) or GUID.
You can just change it to:
public string GetUserDisplayName(string useruniquename)
{
return useruniquename;
}
When you get comfortable with the integration part, then change the above code to something make sense to your system.
