Great initiative tkennedy! I wholeheartedly support you! Personally, I never bothered with audio items aside from my flash radio, but I know a ton of people who were affected by this, and will gladly pass the word. Most of them are not members of TIM however, or if they are I don't know them on both sites, still I'm sure you wouldn't mind that.
To pfunkkillah, based on what I got from this, you don't need to do anything to get your credits back. If the lawsuit is successful, everyone who purchased audio products who was affected (which I'm sure IMVU Staff has a record of all the purchases somewhere) should be automatically reimbursed for their troubles. If IMVU Staff decides to try to sweep this under the rug, after being defeated, and simply leave the option for people to complain and receive a refund (which seems likely based on how stingy IMVU Staff is) than you simply must file a complaint with IMVU Staff. Either way, contact tkennedy and explain to him your situation, and I'm sure if there's anything you need to do personally he'll let you know.
