As far as which dating site best for you, it really depends on a lot of things.
The biggest question is whether or not to use a paid site.
Most people's knee-jerk reaction that there is no way that they would actually pay for a dating site.
I used a paid site and there reasoning for why someone would choose to pay was to remind people that were they to go searching in real life, they would still be spending money.
Granted, sites vary in their pricing, but you get the picture.
Once you decide on a site (or sites) put a lot of effort into your profile: fill out all the fields, post recent flattering photos (updated frequently and proof read for grammar and spelling.
You're a young man who has a desire to find a godly wife.
The example they used was that someone might go out to a coffee shop every week (they were too polite to say bar) in hopes of meeting someone.
For the price of all the coffee you drink while there, you could have gotten a subscription to a site where you would know that everyone is a) the right religion and b) looking for a relationship.
Has anyone around my age had any luck with services like these, or is finding someone in person still the "safe" bet for Christian singles?
I have one or two friends who found significant others online (CM, I think), but not many.
