share links on my website?

[Callum]

O.K, so basically, me and my friends decided to make a website. the main feature of the website is having your own "room" that you and your friends can share links, pictures and videos by posting them in your own "room". However, the only problem is, we no next to nothing about code, so we are using a website builder, its not like one of those online ones, where you pay, its a pre-downloaded program. we just cant figure out how to add a news-feed sort of thing, its like Facebook, but its more personal for you and a few friends, so we want a custom news-feed/wall that people post things to. Is this possible?! is there a HTML widget code thing i can embed? or will i need to learn code and make my own custom coded website?
