Follow by Reader Option not Available

I have recently moved from WordPress.Com to www.ads-software.com. In WordPress.com, we had an option “Follow” on the top left corner of
our blog. If a wordpress user clicks on it, he will see my latest posts on
his “Reader”. I want to have similar option for my visitor. A wordpress
user should be able to follow me via “Reader” which was a feature of
wordpress.com. If I would click on “Follow” I get message “New Post from Blog will now appear on your Reader”.

This feature is different than “Follow by email” where a visitor puts his email address and gets posts update in his email.

Could you please help me get the “Follow” by Reader Option (And not Follow by Email Option) for my blog vistors. This was one of the reasons I loved WordPress and decided upgrading to www.ads-software.com instead of any other Platform, and now I can’t find it.
