Character pages.

I have read more than one post where someone has mentioned that the Mods fact check the submissions before they approve them. Is this so?

I think it depends on the Mod, and how much they actually know about the subject. But once you get over 1,000 points you no longer need approvals.

If you make a submission it's most likely to get accepted as long as it has some validity. Just don't expect the mods to accept any small edits you make (some mods won't approve of it if they don't think the edit is significant enough for merit), but like nobody said, when you get over 1,000 points you can make live edits. 

Thanks.
