Hey, welcome!

Please note that you need to post "within" a community for it to show up there, meaning that just tagging it won't work: /trending/hive-173286

As you can see you need to hit "New post" on the right side there when using the hive.blog front-end. If you subscribe then you can also choose to post within the community in a dropdown menu above the title of the yet to be published post!

PS! noticed your resource credits were low so sent you a little delegation, check hiveblocks.com/@shivandragon for more info on that (a block explorer for Hive).
