first of all, go to https://www.donation...index.php?board=86.0
and start a NEW TOPIC, and put your program name in the topic.
Then, at the bottom of the post form you will see a place where you can browse for files on your pc to attach to a post, including images, and the exe/rar/zip of your program (if you want). If you want, you could include the source but this is not needed.
You can add as many attachments as you want.
