Is a way to do this?

[Ricw]

I have my board set up to use subscriptions.  For spam monitoring purposes, I want to be able to distinguish between free users and paid users.  Free uses would have spam prevention, keycaptcha and question and answer challenges.  Since paid members have to sign up using a credit card, I am not to worried about paid users, using spam and Do Not want them to have to go through spam prevention keycaptcha or question and answer challenges.

It would be nice to be able to turn this on or off by group settings.  Or I am open to other ideas?

Thanks
