How do you search for people?

Same question as the title

To PM, all you have to do is type in their user without the @ and it will have some results of what you think is their username.

Where exactly do you search? i still have trouble finding it…

I have no idea……

Oh under ‘inbox’ there is a button titled ‘start disscussion’ or something like that and then it says ‘title’ (you could just put ‘hi’) and then it says ‘participants’ and you add in their usrnm without the @
