MAL1CE

Copy.com is a good source. Theres a trick to it, though. 1. put together your modpack and upload it to copy.com 2. Right click your .zip and click on share link. the link it provides IS NOT THE LINK YOU PUT IN YOUR MODPACK INFO. 3. follow that link. there is a download link. right click the download button and select "copy link." THIS IS THE LINK YOU NEED. took me some experimenting to figure that out, but its super easy and doesn't require FTP or a hosted website, etc. I hope this helps.
