The Reg Game

Users can join the game during signups by typing /me in in chat.
The host sets the number of players who will answer each question.
At the beginning of each round, 3 random players are selected.
These players vote for a category, and the host randomly picks a vote.
The host asks a question in the category. Only the 3 selected players may answer, and the first to answer correctly gains one point.
This continues until one player reaches a set number of points. This player wins the minigame!

Signups are started with ~plmax [desired number of players].
A player can be added manually with ~pladd [user] and removed with ~plremove [user].
The player order can be shuffled using ~plshuffle.
All remaining players can be seen using ~pl or ~pllist.
A random vote can be selected using !pick [vote1], [vote2], [vote3].
Once the minigame is over, ~plclear is used to clear the player list.
