However, I have found that at least in this Wiki that a word like DavidJRitchie is not turned into a link but one like DavidRitchie is.
I am not sure whether this is considered a feature or a bug but I thought I'd mention it as it took me a while to figure out why a word that I thought was a perfectly fine WikiWord wasn't turning into a link.
It is a feature that prevents all CAP words from linking. It also makes it difficult for the Irish (DaveO'Brian)
You can use the brackets and double quotes method for creating the link as in ["DaveO'Brian"] or DavidJRitchie -- JeffSandys
