 Yes, David good question on the business side. Can you talk about the strategy for bars? I see Microsoft is a trenched with Ecosystem of business partners. Yeah, you just addressed the roadmap of how you're doing that. Sure, you know I think we figured out a long time ago that you know We need a lot of help in the ecosystem out there And there's definitely kind of the developer side which we're starting to do a lot more on you know We do with Google IO and there's a lot more starting to happen on that side that is enterprise related But also just in the kind of classic bar of people that sell and help implement and in the sort of The way I think about it is you know Google always has a very direct model anybody in the world any business can come to Google sign up start using these products And that's great, but there's a large part of the world where And first of all there's parts of the world that are just used to dealing with local people for example in Japan we have a partnership with Fuji soft and and Creasing some others and we largely don't sell directly in Japan other parts of the world We may be selling directly But it's very unlikely that a few hundred person just by way of example a law firm in South hollow, right? They're not going to come and sign up online We're never going to have feet on the street enough to go visit a 200 person company So we need help from an ecosystem. So we launched in the first quarter just a few months back a Program to encourage people to come and they they can sign up get trained and certified and resell apps they get a commission they get a perpetual commission from that and Hopefully they become experts in the product and help people implement things like Google Google sync that you saw today and other parts of the product and so that's really started to take off We've gotten enormous interest or hundreds sign up every week So it's something that's but they only started reselling by the way in April so we just kind of announced it and started to take applications if you will in January and And it's just starting to take off. So it's not it's just in the very very early days, but we definitely view we need to attract an ecosystem because we will We need much much more broad presence out there
