Oh yes I did. I remember my best friend at the time and I got 6-month memberships. It was really fun to be able to play online together when we couldn't hang out. We'd do hide and seek and play the games and such. I wonder how much it has changed haha. I remember when I'd glitch below the chat box and post to people who'd walk by to freak them out. We'd also glitch outside of other areas, too. I think that was one of my favorite things. Also finding all the hidden secrets and such. That was great.
CP was great when I was younger. Played and had a membership for 2-3 years, I believe (started when I was 8 or 9, so I quit by age 12). Had tons of puffles, multiple igloos, good times. I need to get into a game like that again, because god it was fun.
