thanks for the help.
I keep on thinking that wordpress is a blog software, but i guess its just like any other CMS.
Furthermore, what im trying to do now is reduce cost. That means, try to use the software that has the most features that i need already.
BBpress already has categories (different job types) , posts (job posts) , users (companies) and avatars (for logos).
Just way too confused for a person like me who doesnt know anything.
