To comment, you no longer need to be signed into the site first. I figured out how to allow it! (However, if you want to you can sign up using the little Login/Sign up button in the top right corner of the page.)
If you have any other questions/suggestions you can contact me by my email or filling out the contact form on the home page. If this tip list gets too big, I'll either make a new page for it, or put it in the about page.
