The Volcanism on Io article on Wikipedia has been going through a peer review for the last couple of weeks. Additional comments for the peer review and edits to improve the article are useful. In particular, the article's lead section is need of expansion to fit the overall length of the article.
Feel free to improve the article, even if it is just for grammar. Let's see if we can't get two Io-related articles to Featured Article status.
