LO AND BEHOLD!!
AutoResize + Growl + AutoAccept for "MESSAGES" here!!!! [link]
Since Chax wasn't made available to OS X Lion yet, we've been missing some of its features.
A few of them are available in iChat 6 (like the "Show all my accounts in one list" option) or with AppleScripts provided with it (like "Auto Accept.applescript").
This package makes available 2 of the most demanded features in Chax, missing in Lion's iChat, through AppleScript:
* Auto-Resizing Buddy Lists;
* Growl Notifications.
Both are easily localizable to any language: as an example there's a Portuguese version in the package too.
For AutoResize to work it needs to be assigned to both "Buddy Became Available" and "Buddy Became Unavailable" events, on the "Alerts" tab of iChat's preferences.
AutoResize Version 0.5.1
