Is doing pro-bono work a good way to start building a frontend portfolio?

Question

I'm building a portfolio for front-end web development, and have been told that it would be best, starting out, to offer to build site pro-bono for people until I have an adequate level of experience and a large enough portofolio to get paying work.

Where would be some good places to offer to make front-ends for free as I develop my skills?

Answer 1

If you're based in the UK http://it4communities.org.uk/ could be a good place to start.
