I agree - totally!
There must be 1000's of users using this library and suddenly it appears it has been withdrawn along with all the documentation and examples?
I for one, have used this great library in a few projects and it works very well. Lightweight and easy to understand. Why would they drop it? I would like to hear from w3schools as to why this library was so abruptly and quickly withdrawn from their suite as so many users actively use it?
