Somebody said it would be nice if they could make Challenges based on Textivate Plus resources. So we added that functionality :)
(What is Textivate Plus? See here.)
The vast majority of Textivate Plus resources are in French at the moment, and are primarily aimed at UK KS3 and KS4.
Note that Textivate Plus resources require a textivate log-in. With this in mind, you may want to make any challenge based on Textivate Plus resources require a password.
(It doesn't really matter whether or not you do this though, to be honest. If they aren't logged in when they land on a Textivate Plus resource, they will be asked to log in anyway.)
Hope you find this a useful addition.

(By the way, you can already make Sequences based on Textivate Plus resources, using the process described in this blog post.)
