I've added an updated CNB Guatemala on our repository. It includes content as of January 2017 and I've added a search feature, which will hopefully make it much more useful. Please check it out here and let me know if there is anything I need to update before you can make use of it:
Note that some of the formatting could not be preserved when I took it to the offline version. Next time we update, it would be great if I could get access to the server that runs CNB Guatemala, as I can probably build a better version that way. But this update should be a significant improvement over the one you have now.
If you have the latest RACHEL software, you can update this on the "version" tab on the RACHEL Admin page. Cheers!
