I'm assuming anyone registered as Pro in the PSP or NPPL can get the green?
Also, are you applying it to European players in the Millenium too? If so, will all CPL players qualify?
One more thing, with some of them they won't have posted much or have much feedback, but I'm guessing that if they've been checked out to the extent your comfortable you've turned them green then we should be pretty sorted to buy in good faith and be able to rely on the good mods to help out as much as possible should something go wrong?
Edit: Cool idea BTW
