Here are my ideas for Wikia.
Removing spam filter
It is very annoying, and you can no longer add emotes.
At the least, remove it for staff members on wikis. Seriously, every wiki I go on is having a problem with it.
A backpack is a feature where you could upload images into the backpack, so you can keep the images and upload them on different wikis. This could be really helpful in some ways, especially emotes and article images.
A better forum thread history
So it can tell the content of removed replies.
That's all my ideas for Wikia, hope you like them.
