The ease of using this service, it's very easy to navigate through all your folders when you need an upload quickly! Nothing that I dislike about sendspace so far but maybe if there was some way where people could share their account with friends/family members? It would be nice to have other ways than emailing someone else who has access to do something like transferring money between accounts which i think they dont really support atm (not sure though). This works well as long as everything goes smoothly in terms of uploading/downloading content from my computer. You don't always know what will happen after sending such things but since its automated most times you won't experience any problems. If one person gets blocked by another user then you just get notified via e-mail and try again later once unblocked, usually within minutes sometimes seconds. Very convenient.
