Before I buy....can it do this (EasyBlog)?

I want to be able to have subscribers sign up and be put into a particular joomla group.
Then once in that group...only articles created for that group visible to them....just like a regular Joomla ACL.
Also, when it's combined with Mail Chimp and there's a link to an article or an image in MailChimp...and in Joomla that article is only for a particular group....will those not in the group see it if they click from within MailChimp?

I'll have more questions...but this is the first important one I have.

Thanks
Pam
