Welcome to steemit, Mark! Nice to meet you! I really hope you become successful in this platform!
Very interesting that you plan to offer free photography lessons. I am a photographer myself so it would be an honor to learn more from you :) Feel free to check out my blog posts too incase you find something there that interests you. :)
And you can come join my Discord group where we help new members like you get more exposure on Steemit: https://discord.gg/WmxRnc3
If you do not have a Discord, making one is very easy! If you need help setting it up, I will be glad to do so. Great Intro post! Upvoted and followed!
