Welcome, I can see that you have put a lot of work in you introductory post. Congrats! If you want, here is a guide for new people to the platform. I didn't wrote it (it is too good written for me to be able to write it) I encourage all the newcomers to read it.

And just as an advice, beware of spam. Don't do it, and don't let yourself fall for it. These guys did not even read your post, they are just asking for followers. You can check their previous comments if you want to make sure they are not copy - pasting the same message to everybody. Good luck!
