Ok here's a honest opinion
The new interface is nice looking.
The link codes and the promo tools section is cool and straightforward.
The stats section needs work. You cannot check the individual transactions. I'd like to see the country of the join, the exact join time (including time zone), expected rebill time, number of rebills and the rebill dates. Those are present in CCBILL, but not in the new system.
MetArtNetwork can't be promoted in the new MetArtMoney as far as I know. They upsell the network to the members, but you don't get a share of that. It'd be really nice to be able to promote it, it'd sell well I think.
One more thing I hoped to get out of the non-CCBILL affiliate system is that the visitors can join using PayPal, Bitcoin, like for type-in visitors.
That is not so - only credit card is available to visitors that click on affiliate links.
