Truth Social Handles are used by the servers to identify every user. They use the @ as a flag to identify everything in that “word” as someone’s account. When you sign up for an account, it asks you for a username. That username has to start with an @ and can not have any spaces in it.
If you are signing up for a new account, be aware that a capital i and a small L are almost impossible to tell apart, and underlines are a major pain to type on a phone keyboard. Everyone wants a username that is catchy, but if it is hard to distinguish the letters in it and it is hard to type because of spaces and other characters, some users will just move on instead of mentioning you in their Truth.
Some of the difficulties associated with special characters, numbers, etc are overcome with Truth Social’s version of what we call autofill. When you type @ and start adding letters, the server will automatically suggest users that you might want to connect with and you can click on the dropdown to choose that one.
When you fill out your Profile page, there is a place to enter your name. This name is displayed along with your handle on most pages. Some people make it the same as their Handle, and others add special cute things like emojis. You can change your name on your profile at any time, but you can never change your Handle (username).
