The entire group logs into your website. 
We have helped websites triple their traffic using this feature. We funnel all group members through your website in order to pay for their package or see any details. This gives them the possibility to check out your products and services while engaging with your brand. This is the best free advertising you can possibly get.

Email Marketing 
As each group member pays online for your service, you can add their email addresses to your email list. You no longer just get the organisers email addresses, now you have the entire group to remarket to and send special offers.
