Help needed - File sending

Tis the season in which I have to send some sizable PDF files to various folks. In the past, I used ‘Dropload’, but it appears to’ve gone on indefinate hiaatus. Anyone have any (free) alternatives that won’t make a technophobe like me want to pull out their hair?

You can specify how long the files will remain there and just email the link to whomever you want to share the files with.
