This feature has been in the web app since last fall, so everyone should have it now, but I've never written a blog post about it. The basic idea is that when you run a report, you can now stick all those students into a list that's available from the main search page. Here's how it works.

When you run the report, you'll get a list of students, but there will be a button at the top of the page that says, "Add students to list":

When you click it, MIS2000 will send the students in the report to a newly created student list and give you the name like this:

Then you can visit the Student Lists and see your new list with all your students from the report:

You can try this out on the Alabama demo, like I did, or you should be able to do it on your own state system.
