I started roleplaying back when I was thirteen (now 28). I didn't roleplay through AOL, but I fondly remember Invisionfree, Zetaboards, and Proboards. I had a forums of my own at one point. 

But then I became an adult. Had two minimum wage jobs and worked about 60 hours a week on average and had to quit for about... 10 years? Finally have one decent-paying job so I have free time on my hands again... =D
