How do you search for a dxp user?

I was told that I could look through old posts of a user who apparently hasn't been on here in a long time (because I might find some of her posts interesting about a certain topic). How do you search for a dxp user?

Well when you delete your posts delete.

Oh okay thank you. But some people are still on here but just haven't been active in months to years. Just wondering if there's a username search you can do anywhere.

Just go to your profile and replace your name with theirs in the URL

Thanks! : )
