Problem 1 :
I'm using RT for a chat application and I want it automatically scroll til the end of the conversation so that the recent conversation is visible. Or else we have to scroll till the end and then read.
How can I achieve this??

Problem2 :
I want to use multiple coloures. i.e- Other username in one colour and my username in another colour. Like (Yahoo Mess).
How can I achieve this...

Waiting for your help.

Thanks...
