A bit of news for you, at least regarding the technical explanation of what's up currently, with WC Chat:
Yes, it will be coming back fairly soon. ChatBlazer (the hosted application provider) has finished their internal migration, & upgrade of their chat application, and we've received the updated code from CB that we need to implement on our end in order to get it working.
However, because our
Chat is integrated with WC itself (you need to be logged on to WC to use it, and your display name is your WC username, etc.) this involves a lot more work than simply copying & pasting it in there.
The whole look of CB was changed with their newest update too -- so everything that we had in the old CB screen (graphics, etc.) needs to be redesigned &/or otherwise updated.
So, that's the latest update on WC Chat.
