how long is it?

MyLot has been running for about 3 years, I believe. It is a reliable site and always pays. You may find a few people on the Internet saying that it's a scam. This is because they were banned or their discussions deleted for not playing by the rules (of course, they never tell you that!) Provided that you respect the rules, most of which you can find in the Guidelines, you will find it an enjoyable place to be. Just don't expect it to be a big money earner! It's quite possible to reach the $10 payout in a month, though, if you post quality discussions and give quality responses.
