Before I say this, I will clarify I am new to domaining this year, and Riz is obviously very experienced and extremely kind to be so helpful. But two small notes so all have a varied concept of what has been done by myself and others on LinkedIn is we have built between 10000 and 30000 connections on profiles of all people we dont know and never had any issues. This and when a pop up for email before connection happens you only have to enter your email. I assume as that person collects emails. It's a networking site and adding like an insane mad man and not even messaging those people in my opinion will not do any harm and just try to keep to UK and north America for .com and the sectors your into with domains. This will than broaden your 1st 2nd & 3rd connections huge and on top of Riz's awesome ad strategy which I am going to use now. THANK YOU RIZ , you will also have a broad network of tens of thousands for free advertising via posts and your profile banner. Good luck all.
