So if i understood you correctly, you are offering the service of teaching people any of the skills you mentioned in the op free of charge. I just want to get something straight, are you tutoring people who do not have any prior knowledge about it, or people who have already started their journey in them, but need assitance in one or two areas.
Where are you also going to be sharing this info, this thread, PM or off the forum?
Correct. As for who I would be willing to help, it truly depends on the situation. Like I said, if I can help, I will. I can't promise, though, but I'll always do what I'm able. As for where I will share it, that is totally up to whoever needs the help. If they would like it posted here or turned into an article on Medium, I am happy to do so! If they wanted something else done—like an article, proofreading (non-native English speakers could benefit here with releases or articles), or troubleshooting—that would obviously be up to them 100%. I make edits on Wikipedia, mostly for grammatical errors, punctuation, or structure. I am open to any format.
Let me know if you'd like any more info!
