Categories on wordpress

[mouldycheesefan]

Hi my blog is now nearly ready, hurrah.
However when I link a post to a category if I link it to more than one category it sometimes is appearing on both sections on the front page rather than just the primary category therefore looks like a repeat posting.
For example, if the post is about London and the primary category is cities and it is also linked to the category 'European capitals' then it is showing up twice in the home page rather than just in the primary category cities.
Is thee a way of linking so that posts only appear under their primary categories, so that if someone clicks either category they can see London as an option under both, but that it isn't pulling through toa feature on the home page under both?
Thanks

Did you solve this problem?

I'm a web (wordpress) developer and I think there is a way of doing what you want but you'd need a developer.
