I leave my client connected while my computer and the internet works, I am not always there. Most of the time my client sits there all day without anyone else saying anything.
There is another issue though, the web based client (chat link on forum), when used from cellphone browsers, will not show the list of currently connected users, so then people will think it is empty even if it is actually full of people. As a result of this we see people join and instantly leave a lot, sometimes so fast that there was no chance for anyone to even type a letter.
It is indeed shared with Ravishment U, and mostly it is people from there hanging out, though many of them are also members here. Also I am not really physically there when most people are, or at a predictable time (for me or others), so I get it can be hard to know if someone is there. It may require you to say hi, and wait a few minutes to see if someone is around or not for real, most people connect during work and don't have their chat window front and center since they also need to do work.
Anyway I hope more people will join chat and enjoy themselves, as it is now though it is quiet most of the time and other times it can get quite busy.
