I run a couple of wikis here at Wikki:http://hetalia.wikinet.org/wiki/Main_Page
Wiki for Hetalia. My pride and joy I guess you can say! I started this wiki back on Wikia before moving to ShoutWiki and then here.http://parkipedia.wikinet.org/wiki/Main_Page
Wiki for South Park. Needs a lot of TLC.http://spfantasyseries.wikkii.com/wiki/Main_Page
Wiki for a fanfic universe I created for the South Park fandom.http://projecthelsinki.wikkii.com/wiki/Main_Page
Wiki for my original series called Project: Helsinki.
The last two are semi-private. I created them as back-ups for the websites I'm running but I'm considering shutting the sites down since I've been having major issues with my host the last few months. (Plus, it's just so much easier to edit the wikis!) I recently created a new wiki as a separate branch to the Hetalia wiki (http://hetaliafanfic.wikinet.org/wiki/Main_Page
) just a few weeks ago but it's not fully ready to go online just yet.
I'm also an admin on a wiki at Wikia; a position I've held since '08. Though I'm rarely there anymore since I don't particularly care for the wiki anymore and it seems to be running just fine without me. Not to mention I've had some bad experiences there in the past. But that's a story for another time!
