The pseudocode above is no longer really useful as the page format has changed significantly sine ths task was written. Rather than checking '''every''' edit to see if it was a change to the task description, we'll just assume the user that created the page is the task author. This isn't 100% accurate; a very few pages got renamed and recreated by someone other than the original author without preserving the history, so they are misreported (15 Puzzle Game for instance,) but is as good as it is likely to get without extensive manual intervention. Any furtherSubsequent edits to the task description are not credited. As it is, we must still make ''thousands'' of requests and pound the server pretty hard. Checking '''every''' edit would make the task several of orders of magnitude more abusive of the server (and my internet connection.)
 
The task names and author information are saved to local files so it can pick up where it left off if it gets interrupted during processing. As the task creation time (and original editor) never change, don't bother to re-download every time. Just update the category (Draft or Task) as that is the only thing that really changes. If a task name gets edited, manual intervention is required. Either edit the JSON file with the task information or just delete it and recreate it from scratch.
Each stage of the scraping process is saved to local files so it can be restarted without losing all your progress in the event of a timeout or error. If that happens though, you need to manually adjust where to restart the process.
