I need an add-on that will allow me to select one or more usergroups, enter the number of winners, click a button, and have however many winners randomly selected from the members of the usergroup(s) selected.
You can you can select which usergroups can enter and how many winners there will be.
members have to enter themselves though. Maybe you would have a better chance of getting @Snog to add an admin option to manually enter all members of x usergroups to a raffle rather than have a compete new mod made. if thats what you need
