So here is the situation, I have a wordpress blog site that is a few years old, and every user had a different account to post with.
Now what i want is a plugin/script that automatically adds the name of each author as a tag or a category.
So for example if 'Andre' was the author of a blogpost made on my site a few years ago, he should be tagged in that blogpost Tags: Andre, another thing tagged before, etc
The solution needs to work for posts previously made.
Thanks!
