Wikia is testing a new chat option; users will be able to chat with other users.
However, the chat is still in the early stages, and so far it's only available on a few test wikis. I put a request for it to be tested on iCarly wiki, but we need to wait and find out if the request will be accepted.
Still, I was thinking; would we be responsible enough to not repeatedly write "CREDDIE!" or "SEDDIE!" nonstop?
