Hiya @Abi_Sprocketcape! So, it shows you are a "Basic User", not a Member. It takes about fifteen or more days to become a Member, just to show you are active on the community of the forums. When you're a Member, you can post instantly like we do, but if you're a Basic User (oh, how I remember when I was ), you have to wait for your posts to be moderated.
I hope this answers your question and Happy Aether Hunting!
