#1 option: last message in bottom of page

[Anonymous]

And maybe also text input field.

I find it hard to read the conversation as it is now.

What about a frame based layout, where the message window has a scrollbar

------------- scrollable frame -------------
first msg
second msg
...
...
last message
------------- non scrollable frame ----------
input text field
--------------------------

(otherwise nice, efficient thing you made here)
