nrl.wikia.com is a small wiki dedicated to the National Rugby League and the State of Origin. It is not a very active wiki and doesn’t even have an article about every team in the NRL. It has a total of 20 articles with about three redirects and has been around since September 2008. In that period, there have been a total of roughly 112 edits made by 17 contributors. Of these, five have made more than 10 edits. They are:
Rey76 19
JWykes 18
Emosworld 17
209.66.200.45 15
KapitanYnot 12
Only two articles had more than ten edits. These articles include Sydney Roosters with 16 edits and Canterbury Bulldogs with 15 edits. The wiki has gone through several “active” periods that can be seen on the chart below.
If there is an active NRL wiki community, it probably isn’t here. Most likely, it would be found on Wikipedia or a wiki created by fans on their own domain.
