I've just released a free on-line Faction creation and Campaign administration web-site for the Victorian Fantasy Horror skirmish game 'Empire of the Dead' (
http://www.westwindproductions.co.uk/catalog/empire_landing.php) by West-Wind Productions.
'Empire of the Dead' is a skirmish game with a campaign system similar to Necromunda, Mordheim or Blood-bowl. Your guys skill-up, improve attributes, die horrily or get permenant disfiguring injuries

I love that sort of stuff.
The 'Umpire of the Dead' - online at
http://www.umpireofthedead.com - can track Campaigns, create Factions and produce printer-friendly rosters for use during and after the game.
'Umpire of the Dead' runs on Windows, Mac, Linux, iPad, Android phone, or any other device with a modern web-browser. Though some of the edit functionality is limited on touch-screens.
