If you want to add more you can. Edit the header.php file for the header icons. And then edit the widgets/social-widget.php file to edit those. The css is all located in the css/standard.css file.

These are the social icons that we are using:

You can also just download a 3rd party plugin at wordpress.org if you want specific functionality.

i just opened these page pages..i saw at standard css that you have vimeo youtube and other stuff...why is it not available at the theme options...and oh..btw.. can i add new lines in the theme
options > social icons..?

We don't support customizations. Above I have all the directions needed to find areas to edit.

If you prefer not to edit any code that's no problem, just download a 3rd party plugin:
http://wordpress.org/extend/plugins/search.php?q=social+media+widget

how do i place the widget on the header?

Directions for customizing this can be found here:

As I mentioned many times above, we cannot support free customizations. Feel free to send us an e-mail if you want to hire us for custom work. We are happy to provide quotes on time and cost.

thnx
