Ask if you are. If you aren't, change your approach accordingly. Use every resource possible to reach, inform and guide advisees. Use every technique available to communicate with advisees - live conversation, mail and email. Provide them with contacts in the field as well as printed information and text on the Internet.
Inaccurate information is worthless.
Accurate information, which is timely and correct, is invaluable. There is no substitute. Even the best advice offered in a bitter setting may be rejected. Make sure you understand what it is your advisee is saying, asking for, or concerned about. Ask for clarification.
