Allocating Free Site on ProSites

Hi guys,

I have a main site that I would like to have my own subsites run on as well as other users. Naturally it does not make sense for me to pay for my own subsites as the network is mine but I would like access to the plans with more features at no cost.

I attempted to do this by creating a 100% coupon but according to Jude this does not work with Paypal https://premium.wpmudev.org/forums/topic/coupon-is-not-working

What other options do I have to get the desired result?

Thanks
