This is the Original addon that aims to give you alerts about things happening in Cyrodiil.

I'm getting reports that its functionality is being copied..Not cool.. ::sad_face::

Current features:

Alerts when attacks start and stop on keeps/resources. (You get them outside Cyrodiil as well).
Shows amount of attacking and defending sieges at the moment the attack registers on the map.
Alerts when a keep or resource is captured by another alliance.
Alerts about Coronations and Deposing of Emperors (Default is On).
Alerts about opening or closing of Gates (Default is On).
Alerts about claiming keeps for a guild (Default in On) - No more Anonymous Ninja claiming! :D
Alerts about scrolls (taken/dropped/captured) (Default is On).
Optional additional output to current chat tab. (Default is On).
Ability to disable On Screen Notifications and only output to chat tab.
Setting to turn off Notifications when out of Cyrodiil (in Settings menu and fast slash command toggle "/ca out")
All Notifications added as On/Off toggles in Settings.

Many more things and options are planned, so stay tuned!

Developed by: @Tanthul, Leader of the Dark Moon guild, operating on the European Scourge campaign. (AKA: Nodens - Developer of RealBench for ASUS Republic of Gamers)

How to move the addon window:

Use "/ca show" or "/ca hide" slash commands to make the window visible so you can move it in mouse pointer mode (default key binding "."). Position will save automatically.

A small message/protest by the developer

I want to bring to the attention of the PVP players out there the issue with the Scourge campaign. ZOS in an admitted error on their part, killed the Scourge campaign (both EU and NA) overnight after the 1.1.2 game patch was implemented. This had the effect of everyone of us, that spent two months playing there as dedicated PVPers, to be deprived of any sort of rewards, with no ability to catch up on the leaderboards of any other campaign (except the new low duration/low reward one). Apparently Zenimax does not care about compensating the playtime we spent there. We got literally told: "Whoops, run along now". If you want to help please post at the official forum post http://forums.elderscrollsonline.com/discussion/100718/scourge-campaign/ and/or leave feedback in game via the feedback menu. Our proposal is to have the campaign rewards given to all those who were going to get them when the rest of the campaigns end as well. This message is meant to raise public awareness on the issue. Your campaign and your PVP playtime could be next.
