Searching multiple websites at one time

I created a Rollyo account. God, I wish I had known about this less than a week ago so I could have shown my Spanish computer class. What a great way to add credible websites and search all at once (one of our last topics before we finished). I can think of many uses, especially since you can create more than one. At the library, you could create one with local government links... or another of websites related to health... or to antiques so you could price something... or to readers' advisory pages to browse.... WOW, how really really cool.
Many thanks are being sent to our instructors for tuning us on to these. This is awesome!!
BTW, here's mine. It's a cornucopia of different sites but I will finetune them later :)
