Proofreaders Wanted
Mark Lewis is looking for proofreaders to help with the various "3-line" material he produces. I can confirm from personal experience that while users of the material will obviously benefit, any who help out will also benefit themselves from the Chinese practice and research they will be doing. It would be up to you to decide how much or how little time you would be able to contribute to this.
Anyone interested in helping Mark out should email him here.
