Salam, J.
First of all, let me welcome you to the site. You are the second guy from Singapore. I hope you will prove to be just as helpful as your fellow countryman.
As for your question:
The best way to share your games with us is to first make a list over which games you currently have.
Then send the list to either me or Kosta. We will go through it and tell you which games we want, and how you can upload them to the site.
You can either mail us the list or send it as a personal message.
