Heheheh... In my spare time. :)
I'll get back into it sometime this summer and make my third attempt at the
Voice lab. I figure all the new changes will come into that lab here in
June, so I'll give it some time to calm down (and to re-pass the written).
But eventually. It's tiring work trying to keep all that stuff in my head
though! My brain cells aren't designed for efficient filing. (Too much
partying in college!)
