The first release of touchtheWire, a new website monitoring tool, is now available for download at the Opera Community site.
Warning: this currently only works in Opera 9 Beta 2. The latest weekly fixes a bug with selecting the refresh interval, but prevents widgets from accessing arbitrary web server, which is exactly what this widget needs to do. I'll update when this is fixed.
Touch the red wire, see if it's live! This is a flexible website monitoring tool - up to 10 pages at a time, configurable audio alerts, custom update frequencies and status reports.
