Welcome!
First, log in with 'remember me' clicked and take a quiz here. This will assign you to either Newbies, if you do poorly, or Active. It's only 6 questions. Until then, you will not be able to post, only PM. This is designed to weed out spammers and robots.
The biggest rule is be kind! Don't break any laws, cite/credit others, don't spam, etc.
Introduce yourself in the general forum/tag. Do not post links in your first post (spam prevention measure). If you got assigned to newbie, after I'm sure you're a real person and not a jerk I can approve your first posts and move you to Active. Other members can also approve your posts. If you are in Active, your posts will automatically be approved, so try to do your best. 🥰
The motto here is 'citations please', and no cherry picking a single study 50 years out of date either!
