The navigation tabs up at the top of every page, will take you to the sections of our community that specialize in specific handling of various types of posts. Post folders include albums for photos, playlists for audio and videos, and some even let you choose individual cover photos for the folder itself, as well as thumbnails, and embed plus uploading options for the main media being added, edited, replaced or posted.
Additionally, you are able to comment on and rearrange folders and also manage each individual file, plus edit both in turn if you need to. It's very easy to manage or display your own media, or even rearrange what you've added over time.
Everywhere you look, you'll see various navigation pages showing you what context options or menus are available for the page you're viewing. Additionally, you will see hashtags, which are not post tags, but tags like #example that you can add to any post. And you can also mention usernames in existing posts and comments such as @admin for the site creator plus any other member, and can control how and what you are notified about when this occurs.
Let us know if something doesn't look right or you get confused, and we'll help you out.
