Ok, the CHILDES lab is now online and I think it is ready to do.

With respect to what happened in class, with the searches not working, I don’t really know. I tried it again at home and it seemed to be working. Maybe I was just failing to see a typo or something. But I think the command examples that you have in the lab exercise should work, let me know if you have trouble.

The lab can be done just fine without installing anything on your own machine, you can do it all with a web browser that has the ability to copy and paste the results into a file. So, in principle, I think you could actually do this on an iPhone, although I wouldn’t recommend it.
