EndNote X7 training manual depth

I have reviewed the EndNote X7 training manual (enguide-mac-full.pdf) but it does not go in depth. I’ve been using EndNote a long time, but want to have a comprehensive guide. What do you suggest? I understand that phone help is available, but sometimes I have a question on Sunday or late at night and sometimes the wait for assistance is very long. 

I work on the PC version, and use the in program help which I find to be very extensive.  I also use the knowledgebase at http://endnote.com/support/search-knowledgebase.  (and then there is always this forum!) I miss the old manuals though.
