How do I do this?

Hello,
first of all, I’m not sure whether this really ought to be a hack/plugin query. Secondly, I apologise if this has already been covered before, but after hours of number crunching, my brain is exhausted, and the prospect of just trying to figure out the key words to look for is too daunting.
Anyway. I’m trying to find a way that if someone clicks on a link for a specific category, they get the usual results of everything in the category, but then I would also like to have some code specific to that category.
e.g. i have a category called “personal accounts” any time someone clicks that link, i would like to display some text along the lines of: “If you would like to submit your own account, blah blah blah”.
Is this sort of thing possible. I’m sure that there must be a way using if statements, but like i said, my brain hurts. Perhaps someone who is more of an expert on this can help me out.
Thanks
