It’s working for me too now. But on the 13th it was down.
I made the post on the 13th but I’m still on post approval, so the post didn’t show up till it was approved on 28th. I’m writing this on the 1st Feb. But I don’t think this reply will show up for a while if I’m still on approval.
Wikia will give you the option of moving the content to its own wiki later on, meaning you get a whole wiki just on the topic you’re passionate about and not one covering the wider topic of television.
