Until we can get the Mediawiki back up and working, I've posted PDFs of many of the pages here:
https://sourceforge.net/p/electricdss/code/HEAD/tree/trunk/Distrib/Doc/Questions
https://sourceforge.net/p/electricdss/code/HEAD/tree/trunk/Distrib/Doc/TechNotes
These documents contain many useful materials and I recommend all users download these and read them.
