A few tips for you:
1) Don't use forums where article comments are sufficient for user interaction with what amounts to yet another Linux tip blog.
2) Don't use forums for a blog community unless you have enough of an active user base commenting regularly on articles to warrant it.
3) If you can somehow warrant having user forums, try to design your site layout to actually make the fact that you have forums available for usage easy to spot instead of burying it as a text link with a nondescript name in a pile of relatively useless and overwhelming text links that clutter up the layout.

>how can I make these forums actually a place where someone will post their questions.
Become a genuine seasoned expert on a couple topics, post useful and unique information on a regular basis instead of mostly reposting other people's content and showing off your desktop configuration, and build a community of active readers who actually respect your knowledge and want to ask you questions out of that.

That sounds like a good idea, I have been posting some useful Linux tips and I guess I should focus on that instead of just posting Slashdot styled posts about the happening of the moment. I have had a dramatic increase in traffic in the last couple of weeks, so the amount of visitors I am getting is good for me, I am taking notice of which posts are the most popular and I am using that to decide what to post next, I will focus more on solving problems people are having as well as posting useful tips to help out Linux users.
