No, RinkChat won't replace the forum. It's just been quiet here the past day or so. Most of the things that occur in RinkChat are things that would probably never show up here, because of the conduciveness of the two mediums for particular types of conversation.

The forum's lull is characteristic of it since its inception. It happens from time to time. Then someone will start a thread that people take to, and the traffic will blossom again.
