_{Fortnightly Topic Challenges are all water under the bridge now, so we will do something completely different.}

What to Do:

If you have an idea for a tag or a theme of any kind to use as a topic challenge, post it as an answer below. (Do note, you can propose anything, not only a tag). Each answer should start with the title of the topic in a markdown heading (## Title ##). Only one suggestion per answer, please. Here is a list of all tags, to help.

At the start of each month, the highest-voted answer to this post will be selected as that month's topic. Starting from today, users can propose their themes or topics. The selected answer will then be deleted to reduce clutter in the list.

After the selection, a new question will automatically be created in this format. An answer will then be posted to that question with links to all the posts in the featured topic in the fortnight.

We'll again keep a list of all the topics.

Happy Puzzling!

The first MTC will start on January 1st, 2022. In the meanwhile, topics will be gathered and voted on.
