Verification plays a role in member safety and is also a big part of supporting Trip Hopping.
When you make a payment with your credit or debit card, we can verify your identity and put an icon on your profile that let's other members know you are who you say you are. We'll send you a letter in the mail with a code, once you receive it you'll see instructions to enter the code on the site, therefore verifying your address and identity further.
Like we said, this helps support Trip Hopping in a huge way! We use the money we get from verifications to keep our servers up and pay for the various expenses that make Trip Hopping awesome.
To get verified you can pay as little as $25, or as much as $50, $100, or one billion dollars (actually I'm not sure what we'd do with a billion dollars... so just pay what you can and it really helps).
