there are two ways on web interface
1. reply to your own posts
(post a toot hit the reply button to that toot post then reply to the second toot carry on always repling to the last post in your own thread)
2. go to simplified mode bottom right of text input field you'll see a + icon tap that to create a thread and post all at once
in app/mobile step 1 is the only way
