Subscriber AGD sent me this:
http://mytemp.philsworld.de/ is a pretty useful site for getting files to other people when email just isn’t an option. It’s free and requires no registration. The use that comes to mind is when you want to send one or more people from a chatroom a file but do not wish to share your email or web address. The test file I sent over a month ago is still there (http://mytemp.philsworld.de/9229/text.txt, just contains “test”).
I haven’t tried it myself, but if you have a need for something like this, then check it out.
