Well that's because ISO Cellar basically means uploading your game using a file-sharing site such as 4shared or megaupload. Because of the unsure nature of the downloads through a third-party site, we prefer to wait instead for better times when the file hosting will be cheaper and we'd host bigger files.
The ISO Cellar is just a forum section with links to bigger games. After uploading the files, send me the links and i'll add them there. Or you can just post them in the "Requests" thread in the respective forum section.
