Answering questions, as Jessica suggested, is a GREAT strategy. If you're not sure about your answer, just say that in your message:
"I'm not sure if I understand this, but I'm going to try..."
And plenty of other folks will jump in to revise/help/correct. So there's no pressure to have it be perfect. Trying to explain something activitates a different part of your brain than just reading something. How many times have you had the experience of *thinking* you understand something until you have to explain it to someone else and suddenly, you realize there are holes you did not know were there.
Even better, try to explain it OUT LOUD. This activates yet ANOTHER part of your brain not triggered by merely *writing* your explanation. In my classes, I make the students talk things out with each other, teach each other, and write quiz flashcards for each other. The more they try to explain it, the deeper the understanding and the greater the memory retention.
So suggesting that you help answer questions is not just a clever ploy on Jessica's part to encourage more volunteers. (Well, OK, maybe it *was* a clever ploy on her part, but she also knows what she's talking about
Go for it!
cheers and good luck,
