We're all kind of in the same boat (that is, I, at least, am "feelin' ya" [ in other words, I can relate]) ... don't feel bad.
It looks to me like you did ask a question on here. For anyone else who needs to know: you'll need to look for a button like this:
The following locations seem to have this button: The home page: https://board.phpbuilder.com/, and any of the "forum view" pages, such as "/t/php-help", "/t/php-help", "/t/general-help", the infamous Echo Lounge --- "/t/echo-lounge", and the aptly named "/t/7bfc3f5f-bce0-47a5-bca4-becd5cebb41f"
aka ClientSide Technologies.
The confusion likely arises from the fact that you can't "start a new discussion" from a thread/post page such as this page. From this page, your best course of action is to go to the top of the page/thread, and click one of these white breadcrumb buttons: .
Hope this is helpful!
PS/EDIT: Seems we also have some draconian requirements for images. Until they show up/are approved/etc., here are links to them:
