I'm doing some research into the educational use of text adventures. Does anyone know how I can get some data on ActiveLit? How many teachers/students are active, etc?
You'll get your date most likely not here. The specific forum your posted in is exclusively about Quest and mostly concerning coding.
You may however ask in the General Discussion forum, where it's more likely that someone from the staff will see your request: https://textadventures.co.uk/forum/general
But the best thing to do would be contacting them directly by using this form: https://textadventures.co.uk/help/contact
You could also look around on the ActiveLit webpage if that also has a contact form. I hope i could help you.
