I'm not an active editor but I am a very active reader and tend to spend hours everyday reading on Wikipedia and Wiktionary. I'm trying to build up the confidence to edit more often.
Currently I am trying to clear out Category:Articles needing Chinese script or text and resolve all the requests for Hanzi. I also sometimes add characters to pages that I happen to catch outside this category. if you want to give me stuff to do, add [Chinese script needed] to pages that need it, because that category is orders of magnitudes smaller than it should be.
