Adding more types of posts?

Anyone know where in the code I could go to add more types of posts? Basically I'd like to add more 'sub-categories' besides announcements and the normal area so when choosing the post type I could also have for example, a Polls section (just an example) and then when I post a poll I could choose that post type and it would be in it's own 'polls' area just like announcements. I figure it wouldn't be that hard since announcement's is already there so maybe just copy it's code but change the name and add some values in the db for the added post types, unfortunately my ability of manually parsing asp code isn't that great. Any help on this would be much appreciated. Thanks.

That's not what I had in mind. I am talking about this area :


A client I set-up forums for wants to add more of those type, displayed that way, also it wouldn't be efficient to set it up using sub-forums because of the nature of the main forums. the main forums under a specific category will be changing every few months, so it would be a pain to create all sub forums for those forums everytime it changes. It would be much easier to just let the mods of those forums (not me) to set it up how they want simply by choosing from the drop down menu when making a new post (announcements, sticky).

Yes. I know how to create categories. I am talking about specifically within a forum.
When you post, you can choose announcement (this forum), announcement (all forums), and sticky. I would like to add more choices to that specific drop-down menu. Then when you view the forum, not only would it have announcements, and forum topics like in my picture, but also areas for the other types I add. Both of these suggested ways would work the same functionality wise, but in terms of how the content is displayed, my client wants it exactly as I said. And also it allows the mods to set it up as they see fit instead of me having to manually create each forum within category, or each subforum within a forum for all the forums on my board which would be an administrative nightmare considering how many forums there are and how often they change.

Thank you for the reply Bruce, I do with work a developer who is quite good with ASP and I am sure would have no problem editing the code, but as you pointed out, he isn't familiar with the program. Would it be too much trouble to ask which files, even if not a complete list, simply off the top of your head need to be edited to achieve this goal? I don't want to be a huge inconvenience, but since you are very familiar with the program it would be appreciated. My client is 100% stuck on having it this way.
