Detailed Requirements and Limits for Account Passwords

Upon creating an account I was told to make a password that was "at least 6 characters long".

I tried with passwords length 1000, 500, 256, 128, none worked.
At 96, the site would redirect me to a "Error occurred, please backtrack" webpage, but upon backtracking and trying to log in, it seems that the password saved anyways.
At 64, the site updates/creates passwords no dramas.

If the password character limit really is 100, please notify users by specifying length, such as "Must be 6-100 characters long", and additionally, some good security advice such as "Recommended to have at least 1 upper case letter, 1 lower case letter, 1 number, and 1 symbol" or something to that effect.

Cheers,
