I don't see the need for a separate imaginary stories category :?: Categories are for categories of objects, people, and other physical things - not for separating continuites. As nightwing has noted, Fleisher went out of his way to treat everything as one continuity, but with notes pointing out when it contradicts itself.
Well, we are not Fleisher
Besides he was nuts
These stories are not mere continuities; they are not a part of any continuity and never have been and were never suppose to be. Therefore, to include every imaginary tale in the Superman entry would only serve to clutter and confuse that entry. I guess we can have another poll for this if need be.
And asterisk those issues you cited above, Beppo, and send them to the Forbidden Zone page.
This all reminds me of the story of Pandora:
In Greek mythology, Pandora was the first woman on earth. Zeus ordered Hephaestus, the god of craftsmanship, to create her and he did, using water and earth. The gods endowed her with many talents; Aphrodite gave her beauty, Apollo music, Hermes persuasion, and so forth. Hence her name: Pandora, "all-gifted".
When Prometheus stole fire from heaven, Zeus took vengeance by presenting Pandora to Epimetheus, Prometheus' brother. With her, Pandora had a jar which she was not to open under any circumstance. Impelled by her natural curiosity, Pandora opened the jar, and all evil contained escaped and spread over the earth. She hastened to close the lid, but the whole contents of the jar had escaped, except for one thing which lay at the bottom, and that was Hope.
