In the United States, unless you state otherwise, you own the copyright. This applies to any written work, electronic or otherwise. Copyrights are not perpetual, so your work will eventually join the public domain.
You are only required to comply with Rogue's diclaimer to the extent that it complies with the law. As others have mentioned, fair use may entitle you to quote or otherwise reproduce the work.
I'm clueless about other countries, but international copyright treaties generally enforce the copyright laws of the country of origin.
EDIT:
I just noticed that Rogue signs his messages "Hans-Jörg Frieden, Hyperion Entertainment." Doing so implies that he is speaking on behalf of Hyperion Entertainment. If I were you, Rogue, I'd remove "Hyperion Entertainment" from my signature. :-)
