T5Wiki: Name with number before the first lowercase letter
Know-How: Name with dashes in between
Sometimes you have to be creative to find a good name for a WikiTopic. For example, if you want to create a topic about the year 2000 problem, you could go for FixY2K? or YearTwoK? or YearTwoThousand?, but not Year2K or Y2K or Y2000 as a topic name.
