If I have a larger file I want to provide to someone, having my own server, I'll just FTP the file up to the server and then send the link via email but not everyone has that available to them.  YouSendIt.com is cool free service that does basically the same thing.  It allows you to send large files (up to 1GB) to anyone via email.  The file isn't actually sent to their inbox but rather a link to the file that was uploaded the YouSendIt.com server.  Not sure I like that last part about it staying on their server but lets not assume the worst here.  Plus you can “delete it“ whenever you want.

I can really see this being useful for those not real familiar with FTP, those that have a size limit on their inbox, and especially for those not on high-speed connections.

After signing up you will be given a personal file link that you can give out or post on your site so other and send you large files easily.
