Tags

Tags have two purposes:

1. To organize what needs to be done. For example, by searching for all topics tagged with missing-summary, we can easily locate topics which need a summary. Same for missing-example-problems, etc.
2. To help me find puzzles. For example, has-cryptarithmetic-puzzles can be searched for to find all topics containing at least one cryptarithmetic puzzle.

Some things have a state:

• has-X: the topic has X.
• no-X: the topic doesn't need X.
• missing-X: the topic needs X, but currently doesn't have it.

Here are some examples:

• has-summary
• has-example-problems
• no-example-problems
• missing-example-problems

Other tags are used purely for search:

• cryptarithmetic-puzzle
• tangrams

You can use the following PHP code to list all topics containing cryptarithmetic puzzles:

list_topics_by_tag('Cryptarithmetic puzzles', 'cryptarithmetic-puzzles');
