Simple Sinatra app that auto generates my HTML email signature. Created at Railscamp Perth, Nov 2010
This is a simple app created at Railscamp Perth 2010
It automates the creation of HTML email signatures (which are a necessary evil where I work).
Outlook + MS Word's HTML rendering engine creates terrible markup that causes bugs with our recruitment system. As a result, I had to hand create each signature to ensure it has standards compliant markup.
Customise the output.erb file to suit your signature.
Thanks to Carl Woodward and Julio Cesar Ody for your adult supervision.
