Would you like to write something and contribute back to Sage? It's
really easy! Though Sage is free, this is a way that you can easily
give back to the project something really valuable.
Here's a very concrete way you could do this. Take the message you
got that you found unclear/confusing, paste it into a text editor,
improve it so that it would have been a message that would have been
perfect for you (and saved you time), then just send that new version
to us in an email to this list.
This would be greatly appreciated. Thanks!
