I'm going to participate in the challenge starting today.

I've been a member for a while now.

I'm going to participate in the challenge diligently starting today.

But I can't even verify my identity.

They say the nickname I always use is already in use.

Did I sign up with a different account?

I even checked it, but

It turns out that duplicate registrations aren't allowed.

Would it be okay if I got to know you gradually?

I guess I'll have to enter my phone number first.
