I was mainly nervous about the database where I had to manually create tables and I don't know the code well. Fortunately someone provided what needs to be entered in there and I was able to do it.
The only thing that I wish it had was the ability to move categories up and down like the forums -- I saw that someone posted that and the reply - so I should have planned the order better beforehand.
I did find an alternate way to organize it the way I want after all the info has already been entered. Just create a new category (with a similar name - I'm not sure if it will let you create a duplicate and it will be easier if it's not exactly the same anyway) then "delete" the original category and move all the posts to the new one from the drop down box (then change the name to what it was previously if you want). It's not as easy as simply moving the categories around, but at least you won't have to reenter all the posts - only the category name and you'll have them right where you want them. Hope that helps a little if no one thought of it. And if it was already posted - sorry about that!
Anyway KUDOS to the creator! I love it!
