You already hit the spot with the first 10 video selections:
Some additional ideas which might come across better as written guidance as opposed to videos (I can see the sense in limiting the video's to a reasonable number):

• the distinction between STEEM/SBD/SP

• Powering UP & Delegation of SP (Incl. places/ communities/ groups they might go to in order to find or pitch for delegation as a new user)

• The role of witnesses and how to vote for witnesses

• Discord - and how building rapport in discord groups can help foster relationships / not to be afraid to ask for help in discord communities

• places to go for tutorials/ guides on markdown/ how to do the first posts/ the value in the use of the correct and appropriate tags / how to use other medium if they are video content producers

Great to see your progress guys...….
