Thank you so much for the tip on "active in the last", that is the best answer to this problem.
While I respect the idea that, from a marketing perspective, people who are active on this site can bring in the people who created a profile but haven't paid yet, I was just hoping for some method to distinguish between the two groups.
If I know someone is an active member, then I'm going to take some time to write them a more detailed hello that shows I read their profile and am truly intersted in getting to know them. If they are not, a simple "hello" or generic "Chris has reviewed your profile" would suffice. I was not implying that I would ignore or consider talking to the inactive people a waste of time. I'd just rather talk in shorter sentences to them ;)
See my point?
