This feature would allow members to support us and get exclusive content in their inbox WITHOUT having to visit BMC, and will let their accessing the content on BMC be a preference not a must.
If I were not a creator on BMC and were interested in supporting a creator on BMC through joining their membership, I'd decide NOT to become a member if I would have to visit BMC to access the exclusive content I'd be paying for!
Also important, make it possible for us to email the post to MORE THAN ONE membership level AT THE SAME TIME (that makes sense and shouldn't be a problem, since we can make a post accessible by members of more than one level). For example, email the post to level 2 and level 3 members, but not to the members of the remaining level or levels.
