where the training takes 'dives' (not deep) into the other 'hats' an MA might have to put on to do 'stuff' not found in Moodle Admin UX ... like MySQL/MariaDB, or Apache/Nginx/IIS 'tweaks, or PHP tweaks ... etc.
Yes, tons of blogs and how 2's from various hosting providers, etc. but none with 'dives' for Moodle - which, isn't X other popular open sourced software package. Or have I just not Googled the right combo of terms?
Reason asked ... once again volunteered to look at a troubled system after a 'forced migration' (long story). And in conversing with the MA via email and this time via voice (cell phone), felt if the MA had just a little encouragement and a little 'hand holding', could take care of business ... save some bucks and become a little more independent.
