I think he means uploading a flash game, as he’s proved himself capable of creating a thread.
To upload a game:
1. Hover over your name on top right of the screen.
2. Click “Upload a game” on the right.
3. Follow the directions given, including any info you want to add.
Next time, please don’t create an individual thread for your next questions, especially not in this forum. Try googling it, asking in chat, or messaging a mod or admin.
