Integrating website member’s profiles?

[jackwebso]

Hi! I have an accessible website with many register members. I am wondering if you could help me in taking the first step to integrate associate profiles/message to my new and advance database
Is this something that should be coded from scratch? Or is there existing software that I can integrate into my website to make this happen?
I just want something simple like
Member public profile with some personal information
Messaging and add as friend

Thanks in advance
