I don't have time to keep up with my pets anymore, let alone maintain sP. How do I close my account?

= The same question was asked just a few threads down from yours. Honesty though, I wouldn't close your account, you may want to come back later, there's no harm in letting it sit there.

go to preferences, there should be a tab called disable account. There you put in your password and say if you want to disable your account, then disable it

Personal - Site Preferences - Disable Account

There you can self-freeze. After about 10 months your account will be erased completely, until then you by the way also aren't allowed to make a new account here. Bye~:)
