Yes. It will consume some resource credits, so as a new user, it may not allow frequent editing/posting/commenting. Also, while you can edit a post title, the URL will remain the same. All tags except the first can also be edited, or you can add more, too.
I'll delegate some Hive Power so you won't be likely to run short of credits while you get started. Also, your upvotes will start to carry some weight!
Thanks for the delegation as well @jacobtothe!
It looks like you're here to create good content, and that's the sort of thing I want to encourage! I'll remove the delegation eventually, but I hope it helps you get some traction for now! Meanwhile, take a look at some of my older posts from my Hive Pope account. There, I cover some formatting tricks, briefly explain keys, and warn against some common pitfalls.
Thanks, I will check out those posts!
