Nice site, but it’s going to be death on a 56k dialup type account. It took long enough to load on my office connection (T1) that I thought it had locked up.
A couple of your graphics could be clipped better, there’s an awful lot of white specks around the edge from where you picked it out of wherever you took it from.
Also, it might be better to list where you are located, as the only place I could even find an address telling me where you were promoting was on the contact us page.
Finally, if you are representing yourselves for charity purposes, you might want to choose a different picture for your “Who we are” page, you all look kinda thuggish. (Personally, anyway…)
It’s a great concept, and a really nice site, I just might provide an alternative for slower speed viewers.
