I have a question about your support forum.
http://semperplugins.com/support/

I posted a this topic
http://semperplugins.com/support/general-all-in-one-seo-pack-pro-forum/all-in-one-seo-pack-keywords-vs-wp-tags/

Someone replied, but I can’t see the answer.
It says:

** You currently do not have permission to see this post. To obtain access to
Admin posts please purchase a support subscription from Semper Plugins **

When I click on Semper Plugins link it takes me here http://semperplugins.com/plugins, but I don’t see an option to purchase support subscription.

Also, I see a link: Don’t have access to view Admin posts? Purchase a support subscription. When I click on it, it takes me here:
http://semperplugins.com/all-in-one-seo-pack/

And again, there is no place to purchase the subscription.
Where can I purchase it? And how much is it?
