A few things:
 

Hi guys, could you give me a hand on the following things:

a) is there a powerful RSS script. One that would allow me to create XML feeds for single forums, categories, whole forums, etc. Just various combinations etc?

b) is there a way of displaying certain sub forums via. alphabetical order by default? (and maybe with the opportunity of being able to jump to "A B C D" etc.)? These forums could also show unlimited amount of posts as default - whereby other forums cannot?

c) how would I go about building a front end that syndicated certain content from certain forums and categories? The post icon could also be shown along with the title of the text (and maybe the first sentence or so grabbed from the post)? You will also be able to login from the frontend.

d) Can I build new fields that can be filled in and shown in a post - which only appear when posting in a certain forum, and how would I go about this?
