New Plugins

As most of you know we have recently upgraded the server, I for one have always thought an optional PvP plugin would be cool, and would attract members.

Here are 2 PvP plugins that are still alive:

Anyone else have any plugin suggestions?

I am still slowly adding plugins, this is what I have to do:
Fix logblock (some permission issue)
Install ConsoleName
Install a pvp plugin
