So at the bottom of the blog entries I want to list the associated categories like this:
Categories: Cat 1, Cat 2, Cat 3
Easy enough - except I don’t want a comma if there is only one associated category, rather just list the category and NOT a comma:
Categories: Cat 1
Not sure how to pull that off, here is the relavent code snippit so far, which obviously produces a comma at the end of any category name listed (when I only want it between multiples and not after the last one):
Categories: {categories}<a href="http://{path=blog/view}">{category_name}</a>, {/categories}
