I think mrdenny deleted one of my answers and I think it's because I've just linked external material w/o providing a solution.
Nothing to say about the reason, but I think it'd be better to let the user know what is happened.
I just looked through all the answers deleted in the last two weeks, the only two of yours that were "deleted" were questions migrated to superuser. Perhaps you could provide a link so we can take a look?
