When you finished a game, how do you put it on the internet, or into download form, thank you
What you need to include in the download is covered in the Manual, under Distributing your game (http://www.adventuregamestudio.co.uk/manual/DistGame.htm).
To put it online, you'll need somewhere to host it. See the Hosting services (http://americangirlscouts.org/agswiki/Hosting_services) page in the AGS Wiki, or try a forum search - this question comes up pretty often, so a forum thread might be more up to date, and will have more suggestions than the wiki.
Since this isn't a AGS Technical question, and there are already plenty of threads answering it, I'll lock this one.
