I'm new to the forum and I do appreciate you hosting it. I have recently returned to chemistry as a hobby. My ambition was to be a chemist when I was young, however, after school I got bit by the IT bug. Having packed my lab up almost 20 years ago I recently felt the urge to experiment. I'm green, rusty, and just plain having fun. My most recent accomplishment was celebrating my son's fifth birthday and introducing him to vinegar and sodium bicarbonate! Again, I really appreciate the forum and hope that I can offer even a small percentage of what I learn here.
