Hmm, I am having some trouble with Mobile users iphone and users that have smaller browsers.
I added 500p from left in order for me to align with the right side.
Here is a screenshot:

Can this be adjusted?

All adjustments are/can be made via the stylevars

Correct, I've been messed with it for a bit but still can't get it to work.
The only way I can fix this is if I move the social media icons to the left from the right.

now it's working.
Yes i put it into header!

Thanks for your support.

It is possible to add Google Plus Brand page?

BTW for some reason the facebook one is not lined up with the others, I've been trying to adjust it but no success.

Based on your screenshot in your earlier post, it looks just fine to me, and they are all perfectly aligned on a clean install.

They are not aligned anymore, see here: http://www.47r-squad.com/

usml_navnet_facebook_margin
usml_navnet_myspace_margin
usml_navnet_rss_margin
usml_navnet_skype_margin
usml_navnet_twitter_margin
usml_navnet_youtube_margin

Make sure the values for each of these are as follows:

Units: px
Use the 'top' value for all sides: No
Top: 1
Right: 4
Bottom: 6
Left: 10

Actually, upon looking at your css, you need to change

usml_navnet_facebook_margin

So the values are as follows:

Units: px
Use the 'top' value for all sides: No
Top: 8
Right: 4
Bottom: 6
Left: 10

Sweet, thanks for looking into that for me :)
That fixed it, btw is it possible for me to move the icons all the way to the right without breaking the tabs?
