I awkwardly typed a solution on my phone, and submitted. Then it told me I needed to log in. Wasted effort. Should tell you sooner (when you start typing?) or not require login.

#72Very nicely done & useful. I do see folks in Twitter/X posting problems. This is a better solution instead for those hobbyists. Is there a way to share a single math problem as a link in social platforms?
Could you please post links to twitter profiles posting problems?
I'd rather see these problems than all that the algo throws at me currently.

Hey, you should work in ecommerce!

hey - yes! on the homepage, you can tap on the "discuss" link on any problem which will take you to the problem's page. that link is unique to that problem which you can share.

#75Please include the source file.
this will be out soon!

#76Great idea, I would use something like this. Would be helpful to add tags/categories with grade level/difficulty if students want to use this for studying at their level.
categories for all problems are already available. is that not what you are looking for?
difficulty of problems will be out soon. though, not in a way where users will be able to assign the difficulty on their own.
thank you for the feedback!

#77In a more brainteaser/puzzle direction there's wu:riddles [1]. For a site that hasn't been updated since 2009 (!) it's very functional and holds up surprisingly well, aesthetically. [1] https://www.ocf.berkeley.edu/~wwu/riddles/intro.shtml
this is very cool! thank you for sharing this!

#78It's a really nice idea and very good to see a familiar and simple interface, I'm definitely keen to look at this when I'm "idling"! Two suggestions that I don't think have been mentioned: 1. It might be nice to at least acknowledge the source of the problems PDF-wise, no doubt somebody put effort into developing then and the supplementary information (assuming the PDFs are open source) would be useful for learning 2…
1. sources of problems will be out soon.
2. that is an interesting idea. i have been meaning to work on the general problem of letting users work their way through a problem on the website itself.
thank you for your feedback!

#79You wanted a thing, it didn't exist, and then you built it. Kudos to you!
I don't know if part of the goal is to have a growing list of math problems and their solutions or not, but I see that mathjax is loaded to display the questions. It might be a good idea to note this and have a page where answerers can (if they choose) see how to write their responses in mathjax too.

thank you for your words! support for comments in LaTeX will be added soon.
