Ian I have added this to the Gikko Prototype brief - API security - Salt - if you have any additional thoughts please share them 

I thought in light of the services landing page that we want to do - it could work to have two landing pages One for Mobile Services Communication services and one for API security services 

The mobile page can link out to the actual services that can become child pages and not sit in the main menu anymore 
Then have a seperate page for the API security explaining the service, acquisition and link out to blogs that explain everything you need to know about API security - I am not sure of timelines but this could be a good way to overcome the newsletter issue 

Also, it is useful to understand your thinking about newsletter stats - what do you consider a good open rate and what do you suggest to improve the current status so we can consider these things going forward
