Hi Aarom, welcome back.
I made my chatroom debut a couple of days ago. Wait for a few messages go by before responding so you know what the current topic is. If no one's saying anything, say something. It's pretty cool, funny things happen. Like:
<Someone>: (Something about the keyboard home row)
<Bird_Person>: qwertyuiop
<Suffix>: Try again, Bird Brain.
In fact, I'm opening the window to go there right now.
