Thanks. @jontek2: That theme is called "ColdBlue". I forgot where I downloaded it from. Try google'ing it.
The theme is very attractive and it was fine in loading too.Good contents that was interesting and useful too.
nice one, but i think that color and graphical transactions between header and main part are a bit rough, therefore i would suggest adding a light background (atleast at the top, to make a contrast with header) and\or stretching the description block ("Manage screenshots. With small... etc") to the fullscreen, this should work, good luck.
