I've seen around 950-ish online, and I still catch it over 900 or so once in a while. Typically, it's on Sundays during the summertime, which tends to be our active season. I don't think I've ever seen it break 1,000, though. The least I've seen was about 50 users online during our least active hours this past spring (May-ish), which is typically testing season for a lot of our school-age users.
