I get hundreds of files each week. Don't worry about not being able to see what you've sent, that's just a security precaution. I can see them, and I'll check them out before I repost them. Or if you're using Win95 or Win98, you can use the ftp that comes with it. If you use mput, and don't want to be asked about each one, use the prompt command.
Help is another useful command.
Here's another way. Click on the browse button and pick a file to send me. If there isn't a browse button, then your browser doesn't have what it takes to use this method, so don't use it, use ftp or email. Don't worry about not being able to see what you've sent, that's just a security precaution. I can see them, and I'll check them out before I repost them.
