:That's really. really lame. You do realise that the category system is effectively broken, from the point of view of this application. Think about it - I provided the reason my Erdos number is at most four, which is interesting. You want me to add myself to a category, where this information can't be found. I dislike the use of categories to replace other ways of doing the same thing, when categories are worse in ways that ought to be obvious to the meanest intelligence.
