I'll update our records, but for future reference, as we state in the email, you can add the tags at the top of the first chapter if they don't fit in the summary field. That field has a limit of 240 characters, and we understand that you might not be able to add all the tags in. You also can't use the dropdown menu for tags after the initial publishing of the story. It's manual from there on, meaning you have to use the arrow keys to navigate through the summary field to the end, and type in the tags yourself.
It's much easier than if you delete and repost. For example, you lost any ratings, hit count data and reviews you might have had on the original version. Once you delete the story, we can't recover that for you. Most of us on staff are also authors on the site, so we hate to see anyone lose reviews and ratings.
