Well, I figured out how to add my rollyo search roll to my links, it's under my "linking to others" section. Of course this was after I figured out that I needed to refine my searchroll(s), at least for my benefit.
As to future uses for the rollyo function, I can say that at this point in time I have no specific need for it. But I can see the functionality of the searchroll, if you are repeatedly needing to go to certain websites.
And with rollyo, these sites will be available to you wherever you are; so if you are working at one branch one day and another library branch another day you do not have to re-create your favorites list on internet explorer.
