Steve-
I did not make these changes that are being ascribed
to me, and I hope no
one else is reverting them. It certainly seems strange that what I add to
pages now seems to be deleted automatically, and I am being labeled the
deleter. Is HAL 9000 acting up again?
These are your sysop powers at work :-). Sysop have the ability to go into
any user's contribution list, including their own, and "roll back" any
user's edit of an article, so long as it is the most recent edit to that
article (which the "top" marker refers to).
You have accidentally rolled back your own contribution to a previous
revision. Don't worry, the rollback is only a shortcut to editing the
previous version and saving it, so no data has been lost. Just edit the
previous version and save it.
Regards,
Erik
