Thank you for doing such great work in going through the library and making corrections and improvements.
You are welcome. I'm greatly helped by newer sources not available 10 or 20 years ago: maturing Wikipedias in many languages, official websites of organizations, Perfect Weiqi Database, Japanese National Diet Library, Google Translate, Twitter, Facebook and even a tsumego solving AI (Panda Sensei). I myself is learning a lot in the process of correcting the Library.
Just adding to this: while I don't agree with 100% of your edits, the vast majority are improvements to the library, and I'm really glad you're here. You've put in a staggering amount of work this year to improve the collection of beginner exercises!
Some time ago, I found this Reddit thread: I'm starting to get tired of SL. After reading through it, I decided to be bolder in editing SL. Fortunately, cleaning up Beginner Exercises finished in less than a month, much faster than I'd expected.
I'd direct that Redditor to the fact that SL is not Wikipedia.
I also would like to thank hnishy for all the hard work and improvements. I'm also very glad you're here. A little disagreement about a few details is not necessarily a bad thing.
I'd also like to thank you for all the contributions to Sensei's Library!
