Hi,
I'm currently creating a little server for a RP adventure with friends, I was searching for a dice pluggin, but the only one available "Dice roller" is really awkward, almost no good options and customisation possible with it, but most of all: it's terribly ugly. I recommend to find an other one that will be beautyfull and can me more customised. (Edit: the one that I found was outdated :x I'm trying to find a new one)
Hope you'll give a quick answer 
Regards
Renard
