There are two types of editors you can use when making a post - a preview editor, which basically functions similar to Word or like-minded text applications, and a BBCode editor, where you can do all the fancy stuff similar to the trappings of the previous forums located at Sourceforge. To change the editor you start with when posting, go to Profile > Edit Profile > Settings, and select your preferred editor in "Posting Default". You may also wish to take a look at "Enable Drafts" if you like writing long posts. Warning: If you switch between Preview and BBCode editors while working on a post, it may break segments of BBCode like spoilers. For big posts, you may want to pick one editor (I really recommend BBcode) and stick to it.
