Thing 15 - ROLLYO

WOW, what an excellent tool. I find ROLLYO easy and simple to use to create a federated search of free (open source) tools that we use to search for information but have to search each individual website. I am just concerned about the search functionality (limit functions) that is lost. I did not have enough time but would like to see whether one can also create a Rollyo for subscription databases, will test this at a later stage.
