YES! You most certainly can. 

In fact, MemberVault is a great platform for membership sites or groups because it provides you with the ability to track your members' engagement. 

This allows you to know who your most engaged members are as well as what areas of your content are of most interest to your members and which are not. 

Our payment integration feature currently allows for one-time and recurring payments which is also perfect for hosting a paid membership site/group.
