Since we launched WoW.com late last night, we've had numerous people writing in about an issue that has cropped up regarding one of the aspects of our tracking addon. We'll continue to respond to those reports personally as necessary, but we figured it would be wise to get the issue and the fix out in the open right off the bat.
The command that's used for the WoW.com addon's Adventurer Notes function, /note, is a fairly common command used in various addons. For example, Cartographer makes use of it. Since the command overlaps between addons, it causes conflicts and one addon ends up blocking the others from using it. If you've run into this issue, there's a very easy workaround if you're not afraid to look at a little LUA. Don't worry, you won't need to do any serious coding. It's a simple fix, I promise.
