If you feel the need, you can add a free Chatzy chat box to your CC or use it as desired.
If you add one to your CC, you post the chat URL in your forum and members can drop in to see who wants to play/chat. (this works esp. when the CC members aren't on your buddy list)
Here's an example of a free public chat room I made. You just type in your nickname and enter.

Chat rooms will be automatically deleted after a few days of non-usage.
