Niki, I seem to remember that you came onto Channel 2, while Rain and I were chatting on Channel 0. Earlier, we had all been on Channel 2, where I think we are supposed to be, and where you normally enter the chat room. Somehow, we all got shifted to channel 0 where we stayed. I thought I saw you switch from channel 2 to channel 0, but apparently not.
When you come on, you can press the "finger" button at the bottom, which shows who is on all the channels; the channels are listed at the end of each line. You can then see if you need to switch channels, and if you do, you can type, for example
/JOIN 0
I hope this helps.
