# This is a queue plugin written for Mino's Quake Live Server Mod minqlx.
# Some parts of it were inspired by the original queueinfo plugin which was
# written by WalkerX (github) for the old minqlbot.

# The plugin put players to the queue when teams are full or even if match in progress.
# When more players adding or there is the place for someone, guys from queue putting to the game.

# The plugin also features an AFK list, to which players can
# subscribe/unsubscribe to.

# Its the alpha state, so any bugs might happen

# For correctly updating the player tags after using !clan, server needs changed clan.py:
# https://github.com/Melodeiro/minqlx-plugins_MinoMino/blob/master/clan.py
# Also you can use the updated version of uneventeams.py, which will put players in queue:
# https://github.com/Melodeiro/minqlx-plugins_mattiZed/blob/master/uneventeams.py
