Hi folks! The RID Raid project is a group of folks who raid horde side through the real ID system. There is currently only one raid that runs each week (Thursday 7:45pm PST) and that group is working on the Glory to the Ulduar Raider achievement (plus other Ulduar achievements). We've got a system in place for others to start a group for raiding on another night so please don't hesitate to start something up if you're interested.
Last week we worked on Orbit-uary achievement (killing FL with all oribtal towers up) but we lacked the numbers to do it. With a few more dps we're set. Instead we completed several of the other FL achievements (including many people getting another vehicle down for Three Car Garage).
If you'd like to participate in this raid head on over to http://rid-raid.enjin.com and create an account, then make sure to register so I can add you to real ID! (If the idea of Real ID squicks you out, please post on the forum we have set up over there. If one of the raiders is on your home server they can send you a normal invite to the raid.)
