The so called "free" web hosting seem to have inappropriate advertising, this sometimes appears after you have set up your web pages.
Checked out Orcon? They seem to be very good. I dont think they push advertising to people. If they do, encourage your visitors to run a popup-blocking browser such as Mozilla or Opera.
I don't want to FTP in and I would like them to be able to do this from the class as well as home.
If you want to be able to do it "from anywhere" the most realiastic choices are SCP or FTP. SCP is more secure, but there aren't as many clients for this task (especially not for Windows). As Orion says in his post, FTP is simple and pain free. You can maintain a directory of your web site locally, which you just sync up with the remote end by drag and drop. There's a Free FTP client for windows called FileZilla which you might want to look at. Otherwise, assuming most of your students have Windows at home, IE has FTP built in, but it's not really suitable for the task. Craig
