A few weeks ago, I jumped the gun and said that Google Analytics Advisor is posting on WebmasterWorld. Well, actually, it was just a post that gauged interest. Since most people were keen on having Google Analytics Advisor come on board, he's now going to address any WebmasterWorld concerns, according to this WebmasterWorld thread.
Expect to see postings from GAnalyticsAdvisor (otherwise known as GAA), and if you have any questions, you know where to go.
Forum discussion continues at WebmasterWorld.
