Interesting and useful idea. How have you handled licensing? I don't see any mention of it on your site (though I may have missed it), and I see that paulgraham.com carries a copyright mark.
In that case, I strongly recommend taking the site down ASAP, at least until you get things squared away. Then reach out to Paul Graham. Contacting a lawyer would also be good, as it sounds like you could use some legal advice in this area. I don't either, for that matter. I just wouldn't want to be potentially exposed.
Asking for donations + a community purpose suggests that there is a recognized non-profit behind the project. If you contacted Graham, maybe he'd say 'no'. Maybe he'd have suggestions for improving it. Maybe he'd ignore it.
Personally, I'd prefer to hear a human reading the text.
