I created some links (to url or just put a name under file name). Now i have to go to dashboard and then click on links to see them. I do not see what is the point of these links? any idea would be very much appreciated it. thanks .
I’m sorry but you did not provide enough information about these links, where they are situated and why you created them to reply to you. I believe you may be referring to a Blogroll of links to similar sites that you like to visit. If you are logged in as the Admin who registered the blog then there is a Links section in your dashboard that you can access. There you enter the links and create a blogroll which you display in a Links widget.

May I suggest that you follow the step by step learn WordPress.com tutorial prepared by Staff? Here’s the link which is also found on the bottom of your Admin page http://learn.wordpress.com
