Hello.
I hope this post will help lots of your customers and help your team to put into consideration.
ES is a great extension to start up with and I get to see that there might be some things to add up to ES to make it the best.
1. It will be of great help if you could add Escrow payment into ES, this can enable members of the site to (a) transfer money to each other (b) stand as a form of payment for any product listed on the site by members. (c) to buy points from to use on the website which can also be another form of monetizing website. Point can be purchase to buy virtual gifts, read articles and many much more. (d) to stand as medium of subscription to website. Money will be deducted from members account once it's loaded. This can be seen on "Joombri"
2. If you can build a plugin to enable member to transfer points between them. A member whose point is low can request point from another member to be transferable from each other. This can be seen with "AlphaUserPoint" I will appreciate it if you can put this into consideration and many other customers of your extension will be very very delightful to see this updates.
