Generally speaking it is not good idea to date through Internet. People tend to describe themselves in better sight than they are in real and online it is much harder to distinguish what is true... It is better to get to know somebody as a friend first before dating. BTW do you know the new social site JWFind.net for Jehovah's Witnesses? They have this in the site FAQ:
Are we primarily a dating site for singles searching for mates?
No. Though you may find a real friendship here, which may eventually grow even into marriage and the site offers so called 'matching function', dating is not what we site merely promotes. Rather than pursue online dating, we suggest that participants make it their aim to forge friendship and exchange spiritual encouragements which will advance to global unity.
