Hello @nebinmv! This is @traciyork from the @ocd (Original Content Decentralized) curation team. We noticed you shared your first post here on Hive and introduced yourself to the community - congratulations and welcome!
Speaking of community, we have many different ones here on the blockchain, devoted to all kinds of interests. Here's a link so you can check them all out - Hive Communities. But based on what you said in your post, I'm guessing these will be of particular interest to you -
STEMSocial Community (focuses on Science, Technology, Engineering, and Math content)
Haveyoubeenhere Community (travel related posts)
Foodies Bee Hive Community (yummy stuff!)
Hive Pets Community (for posts about your adorable bulldog)
Also since you're new, you may run into an RC (Resource Credits) error when trying to comment/post because you don't yet have enough Hive in your account yet. For assistance with a temporary delegation to get you started, be sure to check out the Gift Giver site.
If you have any questions Nebin, feel free to hop into the OCD Discord server and we'll do our best to answer them, and again welcome to Hive!
