1. Email:

• Users are given a unique email address from which messages are passed back and forth. Additionally, one message can be sent to several recipients simultaneously.

Apply for jobs via the Internet

http://www.state.gov/documents/organization/2094.pdf

• The Internet is becoming an essential job-search tool. Understanding how it works and its advantages and disadvantages will be helpful to the job seeker. • The Internet represents a powerful, fast-changing fluid source of information although it is not without its difficulties and frustrations. Those using the Internet should be aware of the following caveats:

a) The Internet is an ever-changing medium. Sites that are here today may be gone tomorrow;

b) The Internet is becoming more and more commercial. Many sites that promise help for the job-seeker simply want to sell something;

c) One of the Internet’s great advantages -- the ability to jump from site to site by hyperlinks -- may also be its greatest disadvantage;

d) Just because it appears on the Internet does not mean that it is true or accurate.
