Yeah, absolutely, we have a very large and very well-orchestrated and integrated plan that we're executing right now as we prepare for commercial availability. And if you think about that plan, you should think about it really in three major buckets. One is, our efforts around the clinical regulatory activities that need to be executed and that has to do with preparing for an ultimate advisory committee review, as well as any ongoing interactions that we have with the FDA. And given that we made our final submission at the end of 2011, those interactions are ongoing, and they've been very positive and collaborative. The second major bucket of work, if you will, is on the commercial front. And that involves, to your point, beginning to interact with those sales channels, those retailers that we anticipate will carry the product. And in that regard we're talking about the retail pharmacies here in the United States, mass retailers, some large food suppliers as well as we're going to have a significant online presence. I mentioned that we've contracted with a sales agent, an organization that's helping us in managing those calls and those relationships, and will continue to work with us, once the product is ultimately available. But while all that's going on we also have work that we're doing on the advertising front, as well as with public relations. There's stake holder and advocacy work that we're involved in right now. We've got focus groups that we've met with numerous times and that we're going to continue to meet with as we prepare for launch and then even post-launch. And while all this is going on, we also have to ensure that our call center is ready to go once the product is ultimately approved. The third major bucket of work is on the operational front, and that has to do with making sure we've got product that's available when we're ultimately approved. So that includes making sure we've got a robust production plan, we've got the supply chain ready to ensure availability, as well as working with our third party logistics provider and make sure that all those activities are integrated with the call center, with the website, so that we can fulfill our orders and receive payment for those orders. So, that's kind of a high-level overview of the whole integrated plan, and obviously I gave you where we intend to sell the product. So all those activities are ongoing and, as Ron mentioned, we're going to see some incremental expenses associated with those activities as we move out now into the first quarter and in through the first of half 2012.
