Dragon Quest VIII's Offical Fan Site, The Slime Knights

This place is what got me hooked on Dragon Quest VIII. Not only is it one of the best DQ communities on the web, it is also highly interactive. At slimeknights.com, you can participate in quests and other activities in order to earn Mini Medals. Collect enough Mini Medals to collect valuable prizes. I already have enough for prizes myself, and the current prizes range from DVDs, such a Pirates of the Caribean, PS2 Square Enix games, and of course, Dragon Quest Merchandise and more.

The site is very similar to Nintendo's Camp Hyrule, without the map, and all the spam. Plus, almost everyone will be able to get a prize if they try.

Anyways, here's the links:
