Update
Glad to announce an update even before a day of sharing the software. 
For those who have already downloaded the software:
- Step 1: Delete the 'IndiTalk Desktop App.jar' file ( Delete only this one file. Not the whole thing)
- Step 2: Download the following file and put in the same place from where you have deleted the previous file. ( Don't worry about downloading a huge file again. This file is just 100 KB
) Link
For those who haven't downloaded the software, use these links ( any one )
After downloading it, unzip ( for RAR file ) or run ( for self extracting archive ) and open the file 'IndiTalk Desktop Application.jar'
The new feature added is HTML Viewer.

You can read the conversations in your browser.
Steps to be followed:
> Click the HTML Viewer tab on the top
> Enter your Member ID and the surrounding count ( Ex: If you enter the number 7, seven messages before and after your chat messages will also be shown )
> Your browser window (example shown below ) opens showing your conversations.

If you click on the word 'Link' beside a name, you will be taken to the corresponding page on IndiBlogger Archives.
You can view my IndiTalk archive HTML document here to see if it is worthy for you to download the software. 
This method is recommended rather than the other 'Chat Viewer' option.
Currently smileys are displayed as characters i.e.
is displayed as :). I will fix that thing soon ( may be tomorrow )
