Hello, back in April 2021 I created a set of videos which guided people through certain functionality within the Polkadot.JS site, and also the Acala Mandala testnet. Like most of my videos, these are supposed to be very high level, for a newcomer to our ecosystem.

"How to Participate in Parachain Crowdloans! Polkadot, Kusama, Rococo" (this was created when the crowdloan function was live on Rococo): https://www.youtube.com/watch?v=4GSR8mqK44Y

"How to use Polkadot{.JS} Extension | Browser Extension Wallet": https://www.youtube.com/watch?v=BpTQBAyFvEk

"Passive Income | How to Stake DOT / KSM | 15% APY": https://www.youtube.com/watch?v=6Ba-hI2a29M

"Acala / Karura DEX Deep Dive | Utilizing the Mandala Testnet": https://youtu.be/1puQ0RtLz_8?t=46

Thanks for reviewing my proposal.
