I don't have Telegram unfortunately but I've gathered together my Bluffer's Guide series to Hive (although some were made pre-hive so reference Steem) so feel free to point them in the direction of these if you needed to - they are written in non-tech speak:

1. The Rewards Pool, Upvotes & Downvotes
2. STEEM, SP, STU, VP, SBD...WTF? (Replace with HIVE, HP, HR, VP, HBD although WTF remains )
3. Getting Started, Networking and Growing Your Account
4. Keys & Account Security
5. Witnesses, Governance & Forks
6. Using PeakD to Create a Post and Embed Video & Music Players
