The bookmarklet pulls the latest guest requests out of Systematic and charts them on the dashboard. Set it up once, then use it whenever you want fresh numbers.
Nothing is uploaded anywhere. The data goes straight from Systematic to your browser.
Press Ctrl + Shift + B on Windows, or Cmd + Shift + B on a Mac.
Drag it up to your bookmarks bar and let go. Clicking it here does nothing.
Open Systematic, then click Guest Requests in your bookmarks bar. The dashboard opens in a new tab with your data loaded.
Right click your bookmarks bar, choose Add page, name it Guest Requests, then paste this into the URL field.
