Tag-Based Organisation

It is with great pleasure today that a new tag-based organisation system goes live. Starting in May 2020, it has taken nearly one year of hard work behind the scenes and we hope that you find it a welcomed addition to Project Euler.

By default, tags are disabled for all members, but they can be enabled on your account page. You will find a drop-down box giving you three options: disabled, problem matching, and full tags. There you will also find a link: About Tags..., which explains in detail how the new system works.

Given the extent of the project, I would like to add special thanks to urimend who proposed the new system and has led the way from the beginning by guiding the whole development process. He has overseen and tagged the majority of problems along with wrongrook, which given the size of the problem set has been an incredible under-taking. And as always with new innovations at Project Euler, we owe our gratitude to hk, who has helped with tagging and offered his continued wisdom and insights during development.

Although there has been significant testing, with the best of intentions it is possible that there may be bugs or unexpected behaviour when a system goes live. So if you notice any issues, then please report them here.

On the About... Tags page, first line in the answer to the second question, there is a typo: "sovler".

The selection of unsolved problems or other subsets does not seem to work when looking for a specific tag.
See http://81.88.24.251/eulerbug/Euler-Tags-Problem.jpg for an example. I had selected unsolved, but the list shows me all problem for the given tag.

When you are searching tags, all other filters and the ability to sort are temporarily disabled.
