Allows the user to log chat from the game (only logs what the user can see, so they can't cheat and read the text the opposite team is saying in private to prevent cheating).

Features:
Log Chat.
Time-Stamp Chat.
Word Wrap.
Save Chat Log to a file.
Ability to read chat while you are Alt-Tabbed.
Ability to read chat that you have missed because you weren't paying attention or because you were alt-tabbed.
*NEW*Ability to send chat messages from the tool.
*NEW*Ability to set the Window to always stay on-top other windows.

So if I say something damming about myself or somebody else in-game it will no longer be forgotten without any evidence of its saying in less then 30 seconds?

Exactly.
and it's more like 10 seconds. Each chat message has a life span of 10 seconds.
