A "live" article is simply one we're working on. Here you can find an alphabetical list of our live articles.
An article is live if (1) we started it ourselves; or (2) it is externally-sourced (e.g., from Wikipedia), and there have been at least three significant changes in three different places to the wording of an article.
The following are not significant changes: removing unused templates, etc.; spelling changes and minor rewording; deletions; and shuffling text without changing it. It does not matter how many such minor changes have been made. Only significant changes, which involve adding or completely rewriting sentences, can make an externally-sourced article CZ Live.
