Thanks Deano. Modzzz Verification module operates outside any information in the database. A member who wishes to be verified goes to a page where they're given a 5 to 8 digit code. They stand in front of a camera holding a piece of paper containing the code and photograph themselves. The admins can then compare that photo with other photos in their gallery. Dozens of sites use something similar. Simple but effective.
My problem is more complex. As you can guess, tens of thousands FB profiles are probably fake. Guys pose as women, some pose as kids to lure other kids. I don't have that level of concern, but I do have guys posing as women. You know my site and you should know what I mean.
When asked for a photo, they have all kinds of excuses, but the laws of discrimination being what they are, we can't refuse them entry . . . because they may be right!
I may have a simple way around this. Modzzz has a module called Membership Badges and I've written to him to find if it can be used for what I need. I'm thinking of using the badges like a One to Five star rating, with One being very questionable.
Don't loose any sleep, I'll wait until I hear from Modzzz.
