Just so you know, this is not specific to the organization you're working with. I've been doing volunteering for the UN, and it was just the same. We were working on a website, and I was the only with any experience with that. The graphical designer was a student, and the "product designer" was a retired bank manager who wanted to try that web thing. That's just the way it is, skilled people are not attracted by volunteering (unless it's FOSS, for some reason).
There's something in it for you, though : not only it will make you feel like you did something significant with your life, but if you manage to get things working despite the shortcoming of this team, you can make it work with any team. That's a skill (especially if you ever want to hire).
