No, these aren't the guidelines for all categories, in general. Very funny~
What to post in the General category:
First, ask yourself this: "Does my thread fit into any of the other categories on the forum?"
If the answer is no, then feel free to post it up!
Don't worry if you want to post something that isn't tech-related; while this is a forum for the tech community, no one's life completely revolves around technology. Anything goes here!
Remember that anything you post MUST follow the forum guidelines!
Also, if you haven't yet, make sure to introduce yourself to the community!
