Can guides be viewed offline? Perhaps allowing users to export them as PDFs?

I'd hate to put in weeks of work only to find my work lost when I need it due to network issues, the site closing, ect.

not at the moment, but it's a great idea. We oppose vendor lock-in of any kind - so we'll definitely look into adding offline access and export features. Thanks!

A couple more things I noticed after a short play around:

* It's not obvious how to (or maybe even not possible) to find a list of your published guides.

* It's not obvious how to (or maybe even not possible) to delete your published guides.

* You have to publish your guides right away, I doubt anyone wants to read my first draft.

* Your source code editor does not accept tabs which means everything has to be copied and pasted in. Have you though about using something like ace? https://github.com/blog/905-edit-like-an-ace / https://github.com/ajaxorg/ace
