Here are the SQL statements to create the necessary tables (they are
not created automatically):

CREATE TABLE `channels` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `invitetime` int(10) unsigned NOT NULL default '0',
  `channel` varchar(255) NOT NULL default '',
  `mask` varchar(255) NOT NULL default '',
  PRIMARY KEY  (`id`)
) TYPE=MyISAM

CREATE TABLE `spamstrings` (
  `id` int(11) NOT NULL auto_increment,
  `string` blob NOT NULL,
  `mask` blob NOT NULL,
  `added` bigint(20) NOT NULL default '0',
  `flags` varchar(4) NOT NULL default '',
  `comment` text,
  `reason` text,
  KEY `id` (`id`)
) TYPE=MyISAM

CREATE TABLE `cycle_channels` (
  `id` int(11) NOT NULL auto_increment,
  `channel` varchar(255) NOT NULL default '',
  `addedby` blob NOT NULL,
  `delay` int(10) unsigned default NULL,
  PRIMARY KEY  (`id`),
  UNIQUE KEY `channel` (`channel`)
) TYPE=MyISAM

CREATE TABLE `forbidden_channels` (
  `id` int(11) NOT NULL auto_increment,
  `channel` varchar(255) default NULL,
  `addedby` blob NOT NULL,
  `reason` text,
  PRIMARY KEY  (`id`),
  UNIQUE KEY `channel` (`channel`)
) TYPE=MyISAM
