It's a good thing to know French as well as English. I have found in the French forum how to move a category into a group. Bon. Ça suffit.

I've been trying to create subcategories of a given category, but after several attempts I give up. How can you create a subcategory for say the category Salary. I've been playing with types and groups to no avail. The guide doesn't say much about this. Could you explain it for me? Thanks
