-<div class="para" id="p-18">As you will see in our history, Runestone came out of a small liberal arts college.  Class sizes were around 30 students.  A huge number of our courses are high school AP CS courses using the CSAwesome book.  Those courses tend to be in the 10 -- 60 student range.

 <div class="para" id="p-19">Recently Runestone Academy has become a tool for courses at much larger institutions and consequently we are seeing course sizes grew.  I was totally taken off guard in August of 2023 when three courses containing 1000+ students were created.</div>
 <div class="para" id="p-20">We have architected the website to be horizontally scalable.  Which means we can support many thousands of courses at the same time.  So, we can support many thousands of courses, but not many thousands of students in a single course.  We are working on that, but it is a big job.  The good news is that the parts that suffer are the parts for the instructor interface.  The student experience is not affected.  So, if you are teaching a course of 1000+ students, your students will not notice any problems.  But you will.  Further good news, the instructor interface is undergoing a major rewrite, so know that we are working on it, and are now aware that 1000+ student courses are a thing.</div>
