I had coded a script that would accept n websites and get you their Google Page Rank and the Alexa information. There were many scripts out there who would do a similar task but they did not process multiple inputs. So I had to develop my own. And I also allowed the user to select if the pulled out results were to be stored in a database.
Today, I am working on an ASP.NET Forum for my own use - and if all gets completed within the next 5 months, I have plans to make it go live and will run it as a forum for myself.
