Downloaded Jetpack (advertised as "Supercharge your WordPress site with powerful features previously only available to WordPress.com users."), tried to activate it, but it says:
"Invalid email or username.
Remember, you need to sign in with your WordPress.com account, not your http://www.raripps.com/blog account. What's the difference?"
My site is with wordpress.org, the plug in says it is for wordpress.org, yet to activate it, I need a wordpress.com account to activate it?
