The weekly newsletter is hard to read because the the math questions are in MathJax code. The code is not transformed into readable format. It's a bunch of dollar signs and slashes, ...etc. No one is going to take the time to decipher it. So... my suggestion: make the newsletter problems readable as plain old type, or find some way to have the MathJax code interpreted and presented as its intent was.
If the Math StackExchange community doesn't work on this, I'll create a web extension to accomplish this. Stay tuned.
