Based on what I have seen in the forum. There are some Post that I will see some of the boards scared me to make comment, mostly Meta. Because I only see Sr/Hero/legendary members in that board. And some of the threads I saw there are very good for me to at least make a comment but my fear is that, wether is is an offend to do so. So I want to know if I have restrictions on some of the boards to make posts and comments in the forum. And if there is please provide those boards for me so I will be properly guided.
Ahh I somehow understand your frustration since the meta board is predominantly a board consisting about the general improvements about the forum itself. No wonder that most veterans are active there since they are accustomed and open to the idea of any improvements. But hey, this is a forum and any form of opinion is accepted as long as you do not spam and post plagiarized contents!
To answer your question, ask yourself what your goal is. Do you plan on ranking your account; or do you just want to engage into a discussion and share your insights?
If you choose the former, then you can post in any board for as long as you contribute something that is beneficial. If you choose the former, then I suggest delving into topics about the development and technical discussion, mining boards, or the BTC price movement.
