Having started using forms 2.0 over the last few days I have to say that I really like it. However one really annoying thing is that I can no longer block generic email adresses such as @gmail.com/@yahoo.com using the html code I used to embed into the landing page. I think that the ability to select this is the forms 2.0 builder would be great as it would allow you to do certain things like block competitors if they used a generic or their work domain address.
