I have never used sostronk though after making the id… this is the first time I’m using, please guide me what to do and how ?

Once a Steam account has been connected to a SoStronk account, it cannot be disconnected. Also, SoStronk accounts cannot be deleted.
However, for any SoStronk account you can change its alias*, email, password etc so feel free to do that.
