It would be really helpful if there were a Channel Listing command.
For example, typing #CL (or #cl) would show a list of all people in the channel you are currently in yourself.
There may need to be a limit - possibly showing only the first 30 people? So as not to fill the entire screen when you are in a much-used channel.
This would be incredibly helpful, especially with guilds, as it saves people having to ask 'who's there?', and would also show when someone who has been asked to leave a channel is still lurking.
Any comments?
