Hi @Singaravelu Souppourayen,  I am a product manager at Salesforce and I saw your comment on the "Contact to Contact Relationship" thread on Ideaexchange. https://success.salesforce.com/ideaView?id=08730000000BqHLAA0 

I would love to chat with you to better understand your use case and needs. If you have 30 minutes to spare in the next couple weeks, can you email me at julia.zhang@salesforce.com and we can set something up?  Looking forward to chatting!
