I loved the new website.
I maked a little games in Construct 2, but I dont get the way to upload it yet =x
hello so_lie,
if you mean posting an html5 version for people to play, just export from the c2 export button on the top ribbon, and place all the files in one folder. you can move/copy/upload that folder to a cloud host like dropbox, then get a link to the file with the '.html' extension and put that link on the forum. people will be able to play your game from that html link in their browser.
i hope that helps...
