Yep … there's a 'back-door' for 'Independent Researchers', also.
They have to state their qualifications, contact details etc, and then the Philica admins approve/disapprove membership.
Overall folks, I'd let this one go.
I agree with David's comments, and I don't particularly wish to be used to review an 'idea'. I'd prefer to let the real peer-review journal committees do that, before we get into any more messy discussions, here at IIS.
(We've been 'round that roundabout many times, eh ?)
If I were Dan, I'd drop it in at Thunderbolts. They'd love to see it.
As a matter of fact, I think they'd claim ownership rights !

Cheers
