Random Number Generator
 

I'd like to have a random number generator built into my boards.

My users play a lot of RPGs on the boards. I'd like it if it had these features:

Tell it what sized die to roll (4 sided, 6, sided, 13 sided, 20 sided, 89 sided and so forth, so that they can tell it how many sides are on a given die even if it's a preposterous die, like a 79 sided die).

Tell it how many dice to roll.

Tell it how many times to roll it.

Tell it to make results public and archived so that we know no one tossed out results they didn't like.



It'd be a neat bonus if it had a sequence generator too. Kind of like what can be found on this site, except built into the boards.

Thanks in advance for any help anyone can offer.
