Cannot find “Get Tools to Build Apps” to install Napa

Question

I have followed this link to login to Office 365 Preview and has got stuck at installation of Napa as I can't find the Get Tools to Build Apps link.

I will appreciate if someone can help.

Answer 1

Just came across a nice blog which explained it all.
What we need to start using Napa is create a developer site collection from Office 365 SharePoint Admin and get on with App building :)
