Hi people,
I made a site to track progress on SPOJ, and give badges for relevant achievements (such as solving 100 problems or having the fastest solution for a problem).
Here's an example page from the site: spojtweet.appspot.com/user/ricbit
Additionally, you can also link your twitter account with the site, so it can automatically post a tweet whenever you solve a problem or earn a badge. Here's a sample tweet as sent by the site: twitter.com/#!/ricbit/status/155700659126140928
To join, just go to the main page, and search for your spoj user name: spojtweet.appspot.com
All code is open source and available here: code.google.com/p/spojtweet/
Hope you like this tool, I had lots of fun writing it.
