There is a limit on blog categories
I had previously asked if there was a limit and go no answer on a prior thread. So I decided to figure things out myself. I was trying to organize my blog (formally bookmarks) by creating blog categories so that later I could move each group of links into a folder. However there is a limit of 20 categories, so if you had more than 20 folders in bookmarks you will not be able to arrange all of them that way.
