New Typing class site to try out

Try this site out for us?
http://www.sense-lang.org/typing/class/dashboard.php
It is a typing site that has a login for a class, has tutorials and games, and then it should present the results as a chart that Ms Ronald can look at to easily see how people have progressed over the year. If we get it working, we won't need to do the typing tests anymore - the games will tell us and Miss Ronald our typing speeds.

Challenge

Now for the opposite... what does 101101 mean? what about 110001?

So..have you decoded the QR code yet?

Come on guys - someone must be able to figure out a way to solve this one? Anyway...please all vote in the poll on the right hand side. Today's question is what does pressing ctrl-y do? What about ctrl-b? If you don't know, open word and try it out, or else google it.
