You can pre-populate these values by adding them to the URL. The first value you set must be preceded with a question mark (?). Values after the first must be preceded by an ampersand (&). Here are permitted options, and their allowed values:

dq= dice quantity: any integer from 1 to 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 1000
ds= dice sides: 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, 18, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 1000
dm= dice modifier: any integer from -40 to 40 (for numbers greater than -1, do not include a plus sign)
dd= dice deviation: lowest, none, highest, wild, stunt
mdq= minus dice quantity: any integer from 0 to 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 1000
mds= minus dice sides: 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 13, 18, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 1000

dt= dice sets: any integer from 1 to 20
sdt= sort dice sets: 1 (sorts the rolls in each dice set from largest to smallest)
to= Your email address: one valid email address
cc= GM's email address: one valid email address
sub= email subject: a brief message, with "%20" instead of spaces (example: This%20is%20a%20test)

Here is an example of a URL which pre-sets some of these values:

Verify your results - email from the dice server includes a MD5 checksum which can be used to verify that the dice roll sent to you has not been modified. You can type the checksum into the verification page to ensure that the dice results are genuine.
Never accept a roll sent from anyone other than the RPG Library server. If the other player forgot to include your email address when generating the dice roll, ask them to roll again: it's the only way to be sure that they sent you the results of a single die roll, rather than the best of many rolls.
