(From minton.garland51@hotmail.com) Hey,

I heard about SocialAdr from a friend of mine but was hesitant at first, because it sounded too good to be true.  She told me, "All you have to do is enter your web page details and other members promote your URLs to their social media profiles automatically.  It literally takes 5 minutes to get setup."

So I figured, "What the heck!", I may as well give it a try.

I signed up for the 'Free' account and found the Setup Wizard super easy to use.  With the 'Free' account you have to setup all your own social media accounts (only once though) in order to get started.  Next, I shared 5 other members' links, which was as simple as clicking a single button.  I had to do this first in order to earn "credits" which can then be spent when other members share my links.  Then I added a couple of my own web pages and a short while later started receiving notification that they had been submitted to a list of social media sites.

Wow.  And this was just with the 'Free' acc
