Hi! What's DC Database's policy on using fan names? The Superman: Sandman Saga article states that "The Sandman Saga is the unofficial title of a storyline that ran in...(etc)". I can't see — either in that article, or the articles for the issues linked therein — where it's stated that the name comes from.
I don't believe so. User:VicGeorge2K9 may have gotten it from the introduction for one of the three "best of" books that reprinted Superman #233. But, that's just a guess, and said contributor hasn't been active here in over a year.
