Needed updates

Hey everyone! If anyone is interested in helping, here are some things that we are still hoping to implement. We will continue to update this post with any new changes, or if changes have already been completed.

1. Test cases for all problems from 2016+ (need to be renamed to work with the current code)
2. Test cases for all problems from (2003 and below)
3. Many of the solutions from 2017-2024 (some existing also require comments for solutions themselves)
4. Pins to posts, as well as post flairs/topics
5. User profiles, custom roles and organizations (eg: schools)
