Hi there, it's Rafi_3. If you are new, you are more than welcome to read this. If you aren't, you can still read this to rely upon as advice for the future.
So, you just joined Scratch.
Congratulations! It's good to see you here. Make yourself at home - don't feel pressured.
But also realize that you are a NEW scratcher, and that if you want to excel in coding/animation/etc., you have a long ladder to climb up.
Right now, you are what's called an AMATEUR scratcher. You have just begun. You have very little experience and don't know exactly how to present yourself to the website.
That is ok. And normal. Don't feel overwhelmed or anything; that's part of trying something new.
But just consider that right now you are at the first step of the ladder. For every day, week, month, etc. you progress on Scratch, you reach a new step. You slowly make yourself up to new heights.
And then you gradually get more “into the groove” of Scratch. You will feel more secure in your being as a Scratcher, and will have a better idea of what/how to contribute yourself to the community.
And you will be appreciated! People will find you and your projects cool. Whether you make video games, animations, art projects, stories, etc., people from all over the world will come to see your work! You will be a SUPERSTAR!
But just be patient. You will get there eventually if you are patient, obedient to the community guidelines, and persisting.
That is all!
