Hello @japi021! This is @jcrodriguez from the @OCD team. Welcome to hive! Congratulations on making your introducing yourself to the community.
You can explore the communities that you may like in this post: OCD Communities Incubation Program. There is a wide variety of topics, you are sure to find the right communities for your content.
If you are looking for tips and information as a Hive newbie, click here: newbie guide. They are easy to understand and useful for learning how the platform ecosystem works.
You may encounter RC (Resource Credits) issues when trying to comment/post because you don't have enough Hive Power in your account yet. You can fix this with a one week temporary delegation through the Gift Giver Site. Another solution is for the person who recommended Hive to delegate some Hive Power to you.
If you have questions or concerns, you can hop into OCD's Discord server and we'll gladly answer your questions.
Explore the communities, subscribe and post about the topics you like and have fun, I wish you a lot of success on Hive!
