Howdy. Please ask your questions and post your experiences about:

- the Astrometry.net web service (http://nova.astrometry.net)
- the command-line code (http://astrometry.net/downloads/)
- the Flickr group Astrometry (http://www.flickr.com/groups/astrometry/)

When reporting a bug, please include the URL to your web submission, or an example image showing the problem. This makes it much easier to track down.

thanks,
dustin
