In PB 2.6mm, this command has been changed to "pb addbot". Besides, you can open the bot menu with the usual key and select the option "fill server". You will then be prompted with some sub-menus for the details of the bots you want to fill the server with (skill, personality and team). After making a choice in the last option, the server ought to be filled - of course, this will only work if you have waypoints for the map you're going to play.
