As a quick learning exercise and in wanting to build something I wanted to use I have built a microapp in Sinatra.
You can see it at http://sixmonthletter.com
Please have a look at it and tell me what you think or leave feedback via uservoice.
Please forgive me if you find that there are bugs - I've literally just got to the point where I want to release it for feedback before doing any polishing etc.
