Yes, FindRun can open urls.... it involves alias' which are things that many people have a difficult understanding fully (well, at least I do). Mouser answered this question in the forum, but I'm sure he'll be along in a bit to tout their benefits one more time!! One thing that he is hoping to do with the new version coming out is get some more documentation out there. But, until he answers the question, search the forum on the word alias. It will get you where you need to be.
