Reinstating Fanatic Online would be an attention grabber, but it's not a great way for developing fan rules since you're up against a deadline and once published you can't edit it. Some sort of SG news blog might be more useful as long as it was kept active by a group of writers that basically just linked to interesting articles, discussions, showcases and events.
As Rav mentioned, it's content that will draw people, but I do think consideration for the forum environment is needed. It doesn't help for example that you can't see links in posts or the link trees and forum titles due to bad CSS and the messy user details next to the posts. You can't link directly to the category like you can at Warseer (
example) which is very annoying visiting as a guest (
here's a mod to fix it). And what's happening with the rest of the FO articles? It's just little things like this that makes the site feel a little less cared for and unfinished.
Btw the Necro Rules Development forum is still a bit of a mess.

I'd post some of my articles in there to help fill it out a bit but I'm not sure where to post it.
