Just make a one-line answer and close the question. Allow comments on the question. So it won't show as unanswered and no more answers can be made. But about lists, you should find a way like making menus for category based lists. eg: menu > category 1 - questions,, category 2 questions, Tutorials etc. With a blog plugin as in the first answer, all these can be done in a civilized way. Another option is making tutorials in standalone pages and making one page as an archive menu. You can modify the faq plugin to make an accordion style menu.
