If you do need some help then I can mostly be found on Qoto STEM focused Mastodon instance within the fediverse. I do login to the LaTeX forums from time to time. I seem to be on ScienceForums quite a lot these days discussing either Chemistry, Astronomy or Astrophysics.
Note: I am just trying to promote the above websites, I am hoping that my basic chemistry tutorial can complement.
This site is designed to give people a basic introduction to LaTeX, and it does a really good job of doing this. It also integrates with Oveleaf which which a really useful feature.
Learn LaTeX is a new website that aims to give users enough information to get started.
It looks very good so far and hopefully will help build up skills in this area. It won't cover everything but doesn't need to. Hopefully some of my posts will also complement this website.
It is great to see so many fresh resources out there. With the upcoming release of TeX Live 2020 the timing for this could not have been better.
