JWmatch.com is messed up... how can you prove anyone on there is a witness or an elder or pioneer or what not? I wouldnt trust that place....
What I'd like to know is how these people think they could possibly get to know someone well enough online to have any sort of serious relationship with them. Even assuming that both parties are being fully honest (which is an incredibly naive assumption) there's just so much you can't possibly find out about someone online.
You call them on the phone? I donno, I'm not speaking from experience here but they use the online thing just to find someone who they then get to know by other means.
So, my opinion on this matter is that you can only really get to know someone by being around them for a significant amount of time. I just don't think that long-distance relationships work, and if you meet someone on the internet, unless they happen to live near you, I don't see how you could have anything but a long-distance relationship.
