Smeddlesboy on "Adding prefixes to titles in a category using plugin?"

I would like to do something similar to what I found in this post: http://wordpress.org/support/topic/add-prefix-to-post-tiles-in-a-certain-category?replies=5

However not being a professional programmer, I do not want to risk messing about writing code myself - is anybody aware of a plugin that can do the job for me.

In short, I run a Wordpress blog for a school and I want to prefix all post titles that are posted by the careers advisers [to this category: http://newbattle.mgfl.net/?cat=84 with something like "[Careers Vacancy]" to distinguish them from regular posts.
