I never made categories for my blog entries and would like to do so now. Is it possible for me to create categories and move blog entries over into them or do I have to originally post them in a category?
From the looks of things, it looks like you have to categorize the blog post as you post it, and since you can't edit blog posts, you can't change what category they're in. However, if you create the categories you want, you can post in Ask the Staff telling us where you want your current posts to be placed and we'll be able to move them for you.
