Guide to understanding the rules of CB.
Always preview your post before posting and look for any possible reference to any potential category. There are 50 potential selections. Once you've identified the top 10 categories you might or might have inadvertently referenced refer to the ordered priority list of topics. Using a matrix system eliminate those that are lowest in priority and then choose the topic that most closely reflects what you think the moderators are looking for.
Now send am email to El Jefe to confirm your selection. Once he's approved your selection feel free to post.
