Good question. The answer is inside you. With 33 Reputation points, you have already helped people here.
You are like myself; learned from the school of 'do it yourself' / 'hard knocks' / 'what if I do ... OHHH #^#^#^#^##$#%$#%#%@#%' . So even without the "formal training" (GeekU as it is known here), you have a lot to offer.
I will tell you this; if you do join, it will be the most challenging, rewarding and frustrating learning experience yet! Wither you have stacks of degrees in IT / PC or just learned how to turn one on yesterday, the training will teach all and fit all experience levels. Fighting malware is like ordered chaos, in every sense of the words. We understand PCs, OSs, Registry rules and protocols that should be used to make it all work seamlessly; malware producers care only about one thing - $$$. I mean, we now have some malware out there that doesn't even have files but code "hidden" inside registry keys (Win32/Poweliks).
So, My hand is out to you; we need all the good help we can get. http://www.geekstogo.com/geeku/
See you inside, classmate???
