Hello, welcome to the Nexus!
First, thanks for the introduction, it is great to meet you! It is always nice to see people with a chemistry background join the forum. This place likes to dig into everything from the scientific procedures to extract DMT and other substances to the more abstract, philosophical ideas involving psychedelics and what they mean to people personally. It is a wonderfully mixed bag, in my opinion.
As for certain parts of the forum being closed off, there are some measures in place to help avoid spam/bots/trolls. If you were referring to only being able to post in certain areas as a new member, please see this:
Why can't I post in some areas? New members are also not allowed to discuss research chemicals (RC's) until promoted and I believe that sub-forum is only visible to members:
RC Discussion Info. Besides that, there really isn't anything else that I'm aware of that is hidden (
you know...except for the special super-secret-classified sub-forum where Moderators gather to snack on pineal glands) Just kidding, of course! Once you become a full member you can post in any of the sub-forums.
Anyway, it sounds like you are on the right track and know what you want to get out of this place. I hope you are able to find what you are seeking and that you enjoy your time spent here with us at the Nexus!
Good Luck!
