@Pookie, it is set to public, but I do not know of any following. One subscriber. :)
I have been pretty quiet about the channel - my most popular video has close to 400 views, and I started this ~6 months ago just drawing or taking photos/free graphic art and then animating it and adding music (very, very basic).
@NamelessBeing, if you do decide to create a YouTube channel, don't click on links in any comments you might receive. Some insert malware links in comments. Also, make sure to protect your identity if that is important to you.
While I am likely getting way ahead of myself here (and where you might be right now - not to mention that you may already know all of what I am about to write), some other things you can do to promote your offer of free lessons to a wider audience is to create that YouTube channel and then add to it by creating a blog/podcast using WordPress (checkout reverbnation there if interested - it is a blog site that offers a lot of incentives for composers). You can also create a marketplace on FB where you can offer free lessons. All of these accounts can be linked. (There are additional ways to promote your offer using social media ... but I will stop there... and my apologies if I am repeating anything you already know!).
For the actual lessons (either to individuals or a group), you can create your own server in discord (a 3rd-party provider) and use their free audio/video feature (and it is free both internationally and domestically). Within discord, you can also upload videos you have made or link them (from your YouTube channel) and still maintain/protect your anonymity if that is important to you.
I have no doubts that if you do all of this, you may well be overwhelmed by how many people take you up on your offer for free lessons. I would if I could. It has long been a dream of mine to pick up guitar again and play the classical music I have already learned via piano. I would also love to learn traditional Flamenco Spanish music on guitar. In the movie Crossroads, Ralph Macchio played Turkish Rondo (or alla turca) and I was hooked! Also, that final scene in crossroads where they battle it out with electric guitars? Some beautiful music there. : )
Most importantly, please go at a pace that is good, healthy, and comfortable for you! I learned all of this little-by-little over about a year and I am old enough to have an original Nintendo game (the original Mario brothers and duck hunt)! So if I can do it, anyone can : )
I am sorry if this is overwhelming to you right now @NamelessBeing... little steps at first if needed and just some potentials that you might be interested in.
Come to think of it, Mat (@WornOutLife), who is so supportive of everyone here, is also a teacher and, by his writings here, it sounds as though he really loves his job. He could likely offer the same thing if this is something he might be interested in (world-wide teaching and tutoring).
Heya Mat sorry to speak of you with someone else - I just thought that this is something you might also like to do or might be interested in.
Much love to all of you!!!
Thanks again @Pookie : )
