Your statement makes no sense, its a game engine that is in BETA at the moment, the main site listed if informative like another site
if you go to the blog section it has one there, the asset shop one there too, the forums there as well....
Just like any other site it has a informative bit then the support and shop separate... if you code your own there usually integrated, oh can not forget about CMS they have them as well..
So I repeat that your statement doesnt make any logical sense, do you not know how to use navigational buttons to get into sections of the site, support - forum takes you to the forum, shop takes you to the shop, contact lets you email them, this is the usual. http://www.forum.aurasoft-skyline.co.uk/index.php
This is the support forum (above) and has a search box where you would expect one.
