Rong-Chang Li
This site is a directory of other ESL resources around the world. As every English learning resources site contains what the webmaster wants it to contain, no two ESL sites are the same. So if you don't find what you're looking for at Speakoz, visit Rong-Chang Li's site.

English Club
English Club is so packed with information that it is hard to know where to begin. I'd recommend setting aside half a day to look at everything. While it could be called a club, it is more than that. And while they offer automatic newsletters, online courses, tests, quizzes and other things, they also offer teaching resources and products.
