A large law firm, which has many employees, provides a single email address for each
employee. Each employee’s email address is <login>@lawfirm.com. However, the
firm did not explicitly define the format of the login. Thus, some employees use their
first names as their login names, some use their last names, some use their initials, etc.
The firm now wishes to make a fixed format, for example:
that can be used for the email addresses of all its employees. How can this be done
without rocking the boat too much?
