Featured Questions

Hi there!
Is there is a way to let certains question always stay on top?
lie this forum has topic with star, I would like my questions stay on top and than my user's questions.

Since I run a wp multisite, another usefull featur would be having in the main site all the question and than the possiility to embed question within certains category in a page of a child blog.
something like:
- main-blog.com/question/:all question with category "blog1", "blog2", "blog3" etc
- in main-blog.com/blog1/ question I embed questions just of "blog1" catogory
- in main-blog.com/blog2/ question I embed questions just of "blog3" catogory
etc...
