Comments Closed, No Site Membership
In the past, this site allowed comments on exercises. In comments, people could ask for help, propose alternate solutions, and point out problems. However, the site has not received a new comment in the last six months. Since the only reason for site membership was posting comments, that has also been closed down. Closing comments and membership makes this pro bono site easier to manage. If you want to comment, try the Facebook link above. People have posted questions and received answers there. And the contact form remains available for site issues.
