Renee: Now a days you don't even need dice! There are virtual dice roller programs that will do it for you. You just pick the dice you want to roll and your bonuses and penalties, and it rolls it for you.
Like this one. I think they are popular for online gaming.
Roll20 seems to be a whole suite created just for online gaming, and I think it has a dice roller built into it.
I have to admit though, as an old timer, the feeling of the dice in your hand and actually rolling them has what the French would call... a certain something. I can see the utility of the virtual dice if you have a fully remote group using something like Roll20 though.
