Since the description of the plugin is terrible, the customer support is extremely lacking, and the reviews are widely varying, I have some questions about this particular plugin.

1. Does this plugin work with the latest Oxwall version 1.7.2? I see some saying no, so I have to wonder.

2. What does this plugin do besides the brief description of members can earn or purchase credits? For example, what systems on an Oxwall site are these credits used on/for? That's important but some how left out on a plugin that's 2/3 more expensive than most.

3. What can others say about the support of the author who is selling it? My experience in trying to get info so that I can then hand them money is that it's already been difficult, so I'd kind of like to hear from anyone else who has ever dealt with them.

Thanks in advance!
