  Number of rolls:

You can add a description of your roll here to save it in the list of user-contributed rolls:

The description must start with a backslash and a space and will be added as a comment to the saved roll.
See the News thread for an explanation of the format requirement.
If the description already exists, the entry will be overwritten.

Please don't misuse this option. I will from time to time edit the list for junk and trivialities.

See the quick reference guide for details of how to use Troll.
