This functionality You are asking about is build-in podbot mm module, so You don't need to use this plugin. All You need is to have in podbot.cfg:

pb_minbots 0
pb_maxbots 6 (or more in the case You want to have later more bots)
pb add 100
pb add 100
pb add 100
pb add 100
pb add 100
pb add 100

(6 lines adding bots puts 6 bots on the server)

or this way:

pb_minbots 0
pb_maxbots 6
pb fillserver 100

Just remember - pb_maxbots it's only the limit for "pb fillserver" command (it doesn't add automatically any amount of bots - You still need to add them by "pb add" or "pb fillserver" command).
Another thing - settings are with underscore line between "pb" prefix and the setting's name (like pb_maxbots), commands are using a space between the "pb" prefix and the main command (pb add).
