Hello there, and welcome to hive.
It can be a little overwhelming to start off with so feel free to ask any questions you may have; You're best off asking questions early than doing something counter-productive for a period of time.
I often tell people to have fun, apply some personality and effort to posts and to engage a lot on other peoples posts as that is the best way to build your relationships. This will help you build your account and get better rewards too.
All the best.
Thank you, uncle. You're the best
