A: Never fear! You can get an e-mail that contains your user name and password on the Request Password page. Just enter your user name. This is an important reason to keep your e-mail address up to date. If you don't keep it updated, you won't get the user name and password. It will instead go to your old address.

A: Never give your password to anyone. Nobody else needs your password, because anyone can create an account for themselves.

We will not ask for your password. And don't change your password for anyone to get in (including us). We won't ever need your password. If someone needs to ask, they don't belong in your account.

Make your password something that you can remember. If you cannot remember your password, you may wish to consider an encrypted password safe for your computer, PDA, or smart phone.

Make your password difficult to guess. See the guidelines below on choosing a good password.

Don't use a valuable password on this system. That is, don't use a password that could also be used to access your bank account, financial records, or anything else that could be used to harm you or someone else.

A: Try these guidelines:

• Your password should be at least 6 characters long.
• A good password can be constructed with a mix of upper and lower-case characters, digits, and symbols.
• Put a symbol in the middle of a word.
• Think of a phrase from an uncommon song that you can easily remember, and take the first, second, or last letter of each word and cram them together. Then arbitrarily capitalize, add a symbol or a digit or two.
• Deliberately misspell one or more words.
• Use multiple techniques.
• The best password is one that is totally random to anyone but you.

A: Don't use:

• Words from any dictionary in any language.
• Anyone's name or nickname (including your user name).
• Common constructions: "foobar", "qwerty", etc.
• Sample passwords (good or bad) from anywhere (including this document).
• Anything from above (word/name):
• with a character before or after it
• capitalized
• reversed
• simple substitutions (0 for an o, 1 for an l)

Password crackers can crack the bad passwords in minutes.

A: See the document viewing instructions.

A: See the download instructions.

Some of the documents are very large, and may take several minutes to download, especially if you have a slow internet connection.

A: In Internet Explorer 6 and earlier, you may have an icon in the lower left corner of the window. It will look like a little tiny white desktop computer with an animated red arrow pointing to it. That indicates that the document is still downloading. When the icon disappears, it is done downloading.

In Internet Explorer 7, you should have one of two things in the lower left corner of the browser window:

• a green progress bar
• a download icon, which should be labeled "Download"

When it disappears, it is done downloading.

In most other browsers, there will be an animated icon in the browser window that indicates that the download is still in progress.
