I dug up the features of each site listed so far and here are the results:
Stash Network - unlimited space & bandwidth/no banners/any non-copyrighted files accepted although non-html loads with advertisement (including images!?!)/
no FTP access
Freedom To Surf - 20mb space/located in U.K. I think/
NO mp3, exe, zip, etc (only webpages)
Bootbox - 10mb space/FTP access/appears you have to register domain to get free space?! Correct me if I'm wrong.
RedRival - Not currently taking new signups
Datablocks - Can't get to it right now
NBCI - unlimited space/Files over 200kb not allowed/FTP ok/no MP3 (except through "Media Storehouse"
/requires placement of ad banners
Hope this helps a little
Sorry if it doesn't have what you're looking for - I was just looking for a place I can move my site - I need about 200mb or so w/o banners and allows mp3s (yes, they're legal).
Any ideas?
