I am in need for a plug in.... I wanted to ask you are you

Hello I am in need for a plug in....

I wanted to ask you are you using your plugins for profile info page ?

https://premium.wpmudev.org/profile/private/

I was searching and I went to my profile and that is what I'm searching ....

Can you tell me did you wrote it your self ?
or used some plug in ? Which one ?

Thank you in advance.
