Use 'Pay with a like' to allow users to blog

Hi there fellow pressies!

Ok I got another good one here :slight_smile:

I've got a blogging network where I am currently running Pro sites on. Instead of charging users a fee to blog I'd like to allow them to blog just by sharing content every couple weeks (my articles for exemple) using the 'Pay with a like' plugin which provides them with a coupon that gives a 100% discount.

So far so good only problem is that Pro Sites still requires them to pass a payment gateway.

Is there a way to adjust Pro Sites not to do this?

And, if not, can you help me think of a way to do this for example by a sitewide password or something?

Seriously I've been at this ALL DAY :slight_smile: and can't find a way...

Much appreciated and happy holidays,

Nick
