Absolutely. That doesn't violate the CamelCase rules I'm using for my 
LuaWiki, and I had forgotten that traditional CamelCase does not allow 
this. (In fact I've alterned mine to allow words like Jan2005 to be 
legal as well).

Given that, the best way to check is the way you did it. I don't have your 
original in my box anymore, so let me try to recreate it:

    function isCamelCase(str)
        local leftover,count = string.gsub(str,"%u%l+","")
        return count > 1 and string.len(leftover) == 0
    end

I think this is more or less what you had, and that works great. Sorry for 
the confusion.

A quick question: Are you using this to make a Wiki?
