How do you find someone on here?
Google their username with "ask.com" besides it, that's the only way, IF you don't follow them.
I'm here haha Jk you can't search for people on here. You can just look for a recent question or if you talked to them earlier you could look at your old question and answers
As far as i know you cant search people on here but they or you can search for their post an follow them
Can't sorry! But you can follow people
