Do you mean you want to know some good websites t learn Chinese. What a coincidence! I concluded several for my students. I will share them with all the people who are interested in.
(Different Chinese levels with clear types and interesting forms)
(You can hear a short explanation of popular Chinese words and some topics from a speaker)
(This is the home page)
(100 lesson videos; pay attention to the different series below, you will see more.)
(Dialogues, Chinese new words, videos, allegories, ancient poems, idioms etc.)
(Everyday Chinese, Chinese Songs, "In" Chinese, Bilingual News, and Chinese Studio, latest updates, etc.)
(Very simple except the stories and news)
Several people have suggested various sites or resources they have found that are useful.
It might be nice if this were formalized or productized in some way (perhaps dedicated forums in each language area, or a wiki?) but doing it as a thread on a forum is probably enough.
These are a few that I've bookmarked - mostly from suggestions from other people here (apologies that I didn't keep track of who suggested them)
