Help with forum style website

Basically on my website there are ten topics users can post into any of these topics. its kinda like a forum but there is no commenting what im currently having trouble with is creating the posting functionality so the posts all have titles and file uploads and for that to show up on other user’s feeds. I have no idea how to do it

Hello, How far have you got currently?

The simplified steps to do this are:

  1. Create your database
  2. Create the design for the inputs and then add a button to run a workflow
  3. Create a workflow that adds the values of the inputs to the database
  4. Then you can create a page which will search for and display this information
