My cousin, Amber Davis, and her husband, Craig, have a youtube channel dedicated to all things RPG. They have a great video https://www.youtube.com/watch?v=ti0tMb-VBvc with some tips about power gaming for beginners and some good reminders for those of us who have been RPGing for a while. You can find the youtube channel here https://www.youtube.com/channel/UCPOnxJFbbjpEBCYBcl6Vb_g/videos.
Until Next Time,
RJ
