Advice Needed Some questions about forum and marketplace!

Hello! I'm new here and I've almost never used forums so I'm really interested in learning more, so far this is the best forum I've seen. of course, I have a question about earning money on the Internet and I will visit these sections of the site most often. so, I wanted to ask about various interesting features of the forums, I would like to know which sections you would recommend visiting  (I have already read the rules), and I also wanted to know how to sell something on the forums and specifically on this forum, do I need to do any specific actions or just post? I have already tried many ways of making money on the Internet, it's also selling, cryptocurrencies, automatization of something using bots (nothing illegal) and every time I try to come up with something more complicated, more interesting and more useful/convenient for the consumer, as well as me, if I do what has already worked for others, then I want to improve my approach, it doesn't always work out, but we don't live in a TV series either. I'm going to sell telegram, twitter, instagram accounts, other accounts, as well as other similar products. Will I be able to do this on this forum, what problems might arise? Thank you in advance for your response and help! I am not very good at English, I can communicate, but I would not be able to write such a text, so there may be mistakes!
