Although Stewie's Domain is not as good as the original Family Guy site, it still has great features such as hotbars.
Even though All Out Toons is a great site with great features, it is not quite up to date but is still a good site.
Damn You All Dot Net is probably the best Family Guy Forum site out there, plus it has a cool name.
Last but definitly not least, All In The Family Guy has magnificant features like up to date episode downloads, calendars, and alot more. A MUST VISIT!
