:I assume that "why on" was a typo for "why not".  Actually, I think that creating a full list of Space: 1999 actors would have been a better solution, but unfortunately Otto's deletion was within the rules of Wikipedia.  It's unfortunate, but there's not really much anyone can do, aside from making a list.  Yes, it is like asking you to cook the dinner again, which is unfortunate: but now the dinner is in the garbage, and can't really be retrieved.  The category deletion was reviewed, and the editors who took part in the review for the most part supported it. 

 :I know that this is cold comfort, and I feel like Mr. Prosser telling Arthur Dent that the plans for the bypass have been on display at the local planning office.  It sucks, but the house has already been knocked down, and the "vandals, homewreckers and half-crazed Visigoths" were acting within their rights.  The decisions about deletions like these (and the policies which support the decisions) are made by those who have time and energy to devote to tedious bureaucratic arguments.  It's an unfortunate flaw in Wikipedia's system.  But I understand the reasons why the system developed the way it did, and I don't know of a better one.  Do you? —  •
