Well it's OK to do it, but it's a lot less professional, what you want to do is make windows or commands the user could use to enter their preferences, and then save them somewhere (like the registry, or in a txt file).

For example, you make a plus window that has a large text box where the user can enter each nickname they want, seperated by a new line.  You then save that to a file and read it from there every time the script is loaded.
