Werewolf mod:
http://forums.bukkit.org/threads/mech-f ... 060.31841/
Mechanics:
To become a Werewolf, you have to get bitten (attacked) by a wolf or Werewolf at night and contract the Wolven-infection (small chance). This infection turns the Human into a Werewolf when they step outside the next night. It can be stopped by staying inside the night after contracting the infection.
A Werewolf automatically turns into his Wolf-form at night.
A Werewolf can sprint in Wolf-form by using the shift-key.
A Werewolf cannot wield weapons (low damage) while in Wolf-form, but does high unarmed damage!
A Werewolf cannot wield Armor while in Wolf-form, but has a high natural defense! When turning in a Werewolf, the player drops his armor.
When in wolf-form, all wolves are friendly (unless another Werewolf controls them).
Prevents your wolves from being damaged while you are offline.
Werewolves are very vulnerable to “Silver” (Iron) weapons.
A recipe creates an item that cures Werewolves and turns them back into humans, when using the item, there is a 1/4th chance the user is cured. There is no way of telling wether the user is actually cured until the next night.

It doesn't have to be updated to the current version of bukkit to work, its really neat and you can limit the amount of things people can do, Its great for mods/admins and has a few things that you could give normal players, the spells are easy to use without putting too much stress on the server and are practical, you can still get the vanilla feeling while using these mods because you can limit them, and its fair. Even if you don't get the permissions set up, the default is only admins can use it, both sooneey and ace have had experience with this mod on my server.
AND THERES CTF :DDDDDD
