Newgrounds also offers a server to upload files to.
Suzanne's use of Newgrounds
The Salvo Underground Zone And Nerd Network Enterprise uses Newgrounds to host uploads of free MP3 albums from Suzanne Records. Competitors of Suzanne Records, such as Nisa Records also make use of Newgrounds as a file hosting site.
Later albums would switch to MediaFire to host downloads. But later on Newgrounds would be used again after MediaFire compromised the download links of some free albums.
