Many patrons may be unfamiliar with using library computers.
Signage helps ease the transition into using the computer.
Signs also help patrons get started using the computers, thus helping to limit the amount of time librarians must devote to assisting patrons with simple logon questions. This will depend somewhat on your library and your patrons, and you will probably need to experiment a bit to see what types of issues patrons have. Some of the profiles will not be pertinent to your library, plus you will want to limit knowledge of the template and library profiles to librarians. Select the user accounts that will be available to patrons in your library, and create signs that reflect which profiles you want your patrons to use. Keep in mind that some profiles have World Wide Web access and others do not.
