Lonekeeper will need to change his username because he won't be alone anymore if he keeps on doing this for the Wow community. He just collected some great addons that most might like. Here are just some of them: Ace, AceGUI, Atlas, AtlasLootEnhanced, BuyPoisons Remix, CTMod (Master, Mail, Party, Raid, RaidBosses, Unitframes), DamageMeters, EnergyWatch_v2, Fontabulous(I used Myriad at size 78), GBars, KLHThreatMeter, MobInfo(Includes MobHealth), ntmysFixLoadingTimes, Natur's , EnemyCastBar (NECB), Nurfed (Combat Log, HUD), Outfitter, RangeColour, SCT, Titan Panel (Includes all the default ones), UberQuests (Modded).

Installing them is a cinch. You should first exit the game, unzip the files to default folder: C:Program FilesWorld of WarcraftInterfaceAddons, then run. If you'd like to modify some of the addons you can follow the instructions below:
