Does "Subscribe by Email" interact with "Membership"?

Hi guys,

Quick question: I’m about to create a Membership section on this site, for which I’m very likely to use your “Membership” plugin. One of the client’s wishes is that certain content on a post (such as a downloadable file) can only be visible to Members (which is “Membership 101”:wink:. BUT they want users to be subscribed to the site’s posts automatically when they sign up for membership (for which I’d use “Subscribe by email”:wink:. Do the 2 plug-ins interact with one another, or how would I accomplish this? “Remote pings”? ALSO, does “Comments Plus” interact with “Membership” (meaning a person becomes a member of the site, and while logged in they’d be able to post a comment on a post)?
