 do lot of reading on topics such as Agile processes, tools and techniques for software development. Therefore, run searches and visit blogs and other educational website to gather information for my ebook. The problem I have is that sometimes I forget to bookmark the sites I visited which means I go through searching the web again to reference the url.

At the moment, I am learning how to use Selenium and want to make use of its recording function to capture the navigation between sites. I want then to use the captured script to catalogue the sites I visited. I am an amateur Java and C++ programmer and would like to enhance those skills and to use Selenium RC for this exercise. One of the problems I envisage is some links open in a separate window and by clicking others you get pop ups. Has anyone of you used the tool other than automating the testing? Your contribution would be most welcome in guiding me through this adventure.
