I have developed two tools that are available for public use:
- VandalSniper - Counter-vandalism tool for the Linux desktop. (Deprecated, consider using Huggle instead.)
- WatchlistBot - Delivers real-time notification of changes to watchlisted pages to any XMPP account. If you already have a XMPP account (Google Talk is a XMPP service) then you don't need to install any new software!
