I hope this isn't considered a thread hijack, I just wanted to let cwfrizzell (and anyone else who may be interested) know that I've just done a major update to my dice roller for usability. Specifically, I've made it so that instead of filling out 4 different text areas for each die roll you just type in, say, Move Silently:1d20+6 and it automatically parses all the info from that. Most all of it is optional, the only required portion is the d20 (or d5 or what have you). Only restriction is that you can only use a single colon and must use a colon to seperate the label from the roll. If you're not using a label, you can ignore that altogether.
