Wikipedia:Article alerts

Article Alerts is an automated subscription-based news delivery system designed to notify WikiProjects and Taskforces when articles tagged by their banners or placed in their categories enter various formal workflows (such as Articles for Deletion, Requests for Comments, Peer Review, and many more).

For notification about cleanup tags, such as {{no footnotes}} and {{disputed}}, see cleanup listings.
For notification about recently created articles that could be of interest to your project, see InceptionBot.
Search Article Alerts for specific topics that interest you. If you find one, add it to your watchlist! You can also browse the subscription list.

First AAlertBot browses all the workflows in its scope, then checks for WikiProject templates/categories on these pages. If a subscribing WikiProject/Taskforce is found, AAlertBot will update a customized report called Article Alerts for that particular WikiProject or Taskforce. (An example of such a report can be found here.) Reports are updated on a daily basis, and provide brief summaries of what is happening, with relevant links to discussion or results when possible. So it is a good idea to request for a bot to place your WikiProject/Taskforce's banner on articles from relevant categories, so AAlertBot covers more articles. (See also Tips and Tricks.)

Originally, the Article Alerts relied on ArticleAlertbot (coded and updated by B. Wolterding, operated by Legoktm) from September 2008 to April 2010 (see bot approval). Following several months of downtime, a new bot AAlertBot was developed (coded, maintained, and operated by Hellknowz, and co-operated by Headbomb) from December 2010 onwards (see bot approval).

Report issues and problems with the Article Alerts reports on the bug reports page. Requests for new features should be made at the feature requests page.
