I have been reading a lot and I maganed to create the page-templates I need ;-) I even found out how to use a specific template for each category ...
But how do I create a teamplate for alle the post in a specific category?
What I need is basicly to have an "extra blog". All post in the category "wiki" must be used by a template different from all other post.
(and of course; all the post in category "wiki" must be excluded from the post-list, but thats another thing and I think I know how to do it).
