is there any way to make money online apart from ptc sites

Yes, they are and mylot is one of these online opportunities. If interested in others, please add me as a friend and I will inform you about other sites as well.

First of all you should mention where are you from. Because if I will give you some earning sites it may not work to you for your country location. But you can try "Odesk", "Triond" "Freelancer", "Lime Exchange", "Elance", Bukisa" etc. sites. But before joining please go through on their FAQ that if you are eligible from your residing country or not. Wish you all the best.

There are tons of ways! MyLot is a great way to earn, I highly recommend being active here, since it will pay and it is a lot of fun too. I also active on Bukisa as well as this site called Shvoong. But you will get a lot of other tips as well, if you read the discussions here on MyLot, almost everyone here is into online earning.
