My tips to newcomers is to learn first and follow the forum rules. There's a reason why there's a forum rules although some people didn't even follow. Some people really did it intentional like spamming or posting shit posts to reach the post requirements needed in a campaign. Anyway, these are the tips that I would advice to newcomers from your list of tips that I think can help newbies or newcomers.
Check out the pinned posts or guidelines
Finding a way to learn should be the mindset of newcomers instead of waiting for someone to spoon-fed you the information or rhe knowledge.
Concentrate on adding value to the forum
By doing this, many forum members will give you merits so no need to prioritize earning merit because if you post high quality posts then merit follows.
Keep expanding your knowledge
This is related to the first one which is about learning. Asking questions if you find something complicated.
Share your knowledge
The tip is self explanatory which is to share what you have learned to others newcomers and also news, events or something related to crypto.
