Not completely, but you can set it to higher value.

if i type letters, it lag a little bit. some users didnt have it but me and some others who write very quick/fast.
(sorry for my bad english, iam german)

There seems to be a path issue with the icon next to the date/time stamp. Can you point me in the right direction as to where I can find this path? I went through the templates and could not find that particular image path.

Thanks Valter, it now maximizes.

It uses old/new icons from style's images/statusicon folder:
post_old.gif
post_new.gif

First....Thanks For The New Update Valter...

;)

We're supposed to change colors in CSS these days, but the title can be changed in Phrases. AdminCP>Languages and Phrases>Search in Phrases>"Chatbox" leads you to vsacb_chatbox - just hit the Edit button next to it.
Try "<font color="red">My Shoutbox</font>".

I did a complete search for post_old.gif and post_new.gif in the code and it shows as "not found" on the following templates.

vsa_chatbox
vsa_chatbox_archive_bit
vsa_chatbox_bit
vsa_chatbox_input
vsa_chatbox_status
vsa_chatbox_topchatters_bit

Valter is there a way to change the text input box from White?

Great upgrade btw!
