I often use www.filesend.net
Register with any daft name and password and for free you get 300 meg of space in which to Upload
files. If you pay you can have 1 gig of space.
Then you enter the email address of the person you want to receive the file and filesend.net will send them an email with a link. When they click the link they can download the file. The recipient does not have to be registered with Fielsend to be able to download
Multiple recipients are allowed, although I have not used that facility.
There are a few adverts and the up/ download is not fast but I have used the system to send PowerPoint files to 70 Meg with no problems. I have tried many other file types and all seem to be accepted.
