I have been working with a military contractor and doing some special coding and one thing they impressed on me is the use of Google and all the apps.
One thing that I will be really using after this will be Google Forms. They embed nicely on the site in a page or a post and come with some amazing features for marketing and networking. If we have time Sunday I will show you some simple Google Form examples that you can use inside your WordPress based website.
