referring to a site which seems
not to be, or include, a wiki.
However, it still refers to, or is
pertinent to the subject of wikis.
Not to be confused with category: Wiki.Wiki

It has a higher than average annual fee to hold the domain (presently $32.99),[when?] that perhaps encourages communities to *want* to work collaboratively.
