Multi Line Text Messaging Input Box

[brandont]

This past weekend I was looking around for upgrades, hacks, software, etc. I found a post somewhere that said you could expand the text messaging input area to be larger, thus allowing you to read the whole message you are about to send. It was a registry setting / hack. But now I can't find it. I've been looking for 2 days and I'm lost. Can anyone direct me to that hack? TIA!
