Actually I would like very much to thank you for the very nice site of yours.
However, a few more things are missing:

1. Some indication when a player is online.
2. Board "Analyze mode"
3. Changing board appearance.
4. Viewing player games (at present we can view a short profile), OOPPSS, I found it…
5. Graph showing player rating (ELO).

Allow me to thank you one more time for the site; I enjoy very much of being here.
