username_0: This is a wonderful place to look for resources about data science education.
 I really hope that the author is still active because some links are broken in README. There are quite a number of pull requests that has not been well-addressed, and I wonder if I should contribute to this repo.
<issue_comment>username_1: Clare just updated the repo 14 hours ago. So, looks like it is indeed actively maintained. 

So, pl go ahead and send in your contributions :)
<issue_comment>username_0: Good to know that!<issue_closed>
<issue_comment>username_2: Thanks for contributing pull requests when you see broken links, I appreciate it!
