Please try https://www.xiangqi.com - we are a new site, and we release new software every Friday. We are still in Beta test, so arrange to meet a friend there. The site is most popular in the mornings (US) and evenings (China). You can meet our team on Saturdays 9-11am ET (9-11pm China).
Here is a nice YouTube video about xiangqi that we created.
