There is something we aren't communicating correctly between each other.
Let me try to explain:
By default the Arras theme uses categories to post your content through the different content areas (i.e. Slideshow, Features 1, Featured 2.... etc.) In the theme options you can set these different areas to display posts from certain categories or by showing stickied posts. The theme does not support pages by default.
Based on your website it appears that you have the following categories: (If I'm not mistaken)
Bjór 101
Bjórmenning fréttir
Bjórmenning spjallborð
etc.
You need to set featured post #2 to one of those categories for it to show up in that content area on your homepage.
This is how the Arras theme works without and custom PHP code edits.
What I had suggested previously was that you make a private page or create a new category and put your "member" posts into that category and leave that box unchecked in the arras options. This is the solution with the default theme.
Does this make sense or am I still confused as to what your problem is?
