I saw this on the Brookland list: Free computer classes for low-income youth.
Byte Back in the Brookland neighborhood provides affordable, hands-on computer training. This work enables economically disadvantaged adults to acquire marketable skills — and thus, jobs.
They have a whole bunch of different classes, including HTML, which I would like to take.

They also accept tax deductible donations. They also have a Contact Us link. It you have a teachable computer skill, consider giving them a call.
