I agree with Bidawinner, and would like to add that my mother ran a wonderful Black History program at her church every February and its now carried on by the youth department. It was a great exercise to help her with every year, and if you were to take the step of creating activities that foster pride and acknowledgement of history for black familes, you could really have a runaway hit on your hands.
I helped create and run the Family Resource section of SmarterKids.com for a while, and I think one of the most wonderful sections was the Activity Calendar:
http://www.smarterkids.com/rescenter/
http://www.smarterkids.com/rescenter/calendar/calendar.asp
There is an activity for every single day of the entire year. You could easily get away with far less work, while adding an extremely wonderful efficacy to the enjoyment of your site by visitors. vBulletin's "calendar" feature, or any number of free calendar scripts on the web could get you started.
Contact me if you're interested in hearing more. I have a number of drawings I've done for my mother of black pioneers you could put up on the website for "coloring" activities parents can download and print. They're line drawings, and perfect for that. Kid sites are fun and they're are a number of "staples" that help them along.
Also, consider registering with the ICRA to get your site "labelled" as a KIDS site (
http://www.icra.org/_en/label/ ). This will help you from being automatically "blocked" by accident. Also, publish a privacy policy when you can.
While one wouldn't want to encourage separatism (I agree with Bidawinner's sentiments), promoting differences in culture is important and educational. Sometimes its learning that helps bring us closer.
