Thought I'd share this one with you. The forum was the first place I check for help with deleting a category with many dependencies, but unfortunately I couldn't find anything. So I wrote my own blog on the problem.
The article takes you through the steps, decisions and SQL needed to delete a category.
So the next time you, try to delete a category and you get:
The following relations prevent deletion:
* 44 posts within category through main cat
* 44 posts within category through extra cat
then you will know what to do.
