Alternate download link
As Curse has been very unstable for downloads lately, I have set up an alternate download page carrying the latest version of my addons. You can find it under http://www.ursbeeli.ch/m_addons.shtml

History
On August 10 2007 john.ra reported in alt.games.warcraft the URL of the following reputation calculator.

http://reputation.mygamesonline.org/

I thought it was awseome. Unfortunately it went offline for quite some time due to over-traffic and during that time I had the idea that it would be very neat to have something like this, especially considering that the information to calculate everything was more or less available from the WoWWiki faction pages.

Urbin, Dun-Morogh (EU)

Features
This addon displays how many reputation points are missing to the next reputation level in your reputation window. In addition, it extends the reputation detail window by showing how many points you need for your next reputation level and how you can best gain this reputation. It also shows how much reputation you can gain by handing in completed repeatable/daily quests and gathering quests.

Thanks
To Shanti, Luidor/Dougi and Milamber from <Hüter des weißen Feuers> on EU-Dun Morogh for helping me with the German faction names.

Shattered Sun Offensive Phases
As of patch 2.4 there are new daily quests for the Shattered Sun Offensive. These daily quests change depending on which phase your realm is in. Also, for some of the phases, there are sub-phases. You can find out in which phase and/or subphase your realm is in by talking to the NPCs on the Isle or to the NPC standing next to the portal to the Isle in Shattrath.
You can set the phases as follows:

/fiz phase 1 - While capturing the Sanctum
/fiz phase 2 - While capturing the Armory
/fiz phase 3 - While capturing the Harbour
/fiz phase 4 - After the Harbour has been captured

/fiz phase2b 1 - While building the Sunwell Portal
/fiz phase2b 1 - After the Sunwell Portal has been built
/fiz phase3b 1/2 - Anvil and Forge (1=building, 2=built)
/fiz phase4b 1/2 - Monument of the Fallen (1=building, 2=built)
/fiz phase4c 1/2 - Discovering Roots (1=discovering, 2=discovered)
