You register a new forum account, you're a forum newbie. You can be a Bitcoin expert before you register an account or the opposite, doesn't matter, you're still a forum newbie. ("You" in a broader sense...)
Of course, as an "expert" with knowledge to share and helping others and being able to contribute merit worthy posts, posts that add value to the forum, those with knowledge and ability to write nicely will rank up likely faster.
I was of course once a forum newbie, too, and learned about Bitcoin around 2011 with way less knowledge about it back then. My current account is far younger, though, nothing wrong with reading silently for a long time.
My main focus in this forum was to read and share interesting things about Bitcoin, to learn and to share knowledge once learned. If you focus too much on ranks, you're gonna likely have a hard time and less fun here.
For a start to learn more about Bitcoin, hop to
https://learnmeabitcoin.com and work through Beginners and later Technical sections. There is a lot to learn on that site if you want. I visit this site even after years regularly and to refresh memory and details.
Books like "Mastering Bitcoin", available on Github, are another source if you prefer that. I don't give you a link, try to find it yourself, it hones searching skills.
Also practice to search things in this forum either by
Search or by using the marvelous external site
https://ninjastic.space.
Take your time and enjoy reading interesting topics in this forum. There are a lot of them (sometimes a lot of garbage, too).
