Update: There are apparently problems under Windows XP as well, calling for a bit of file editing (?).
Supposedly there is a problem with the YIP Copier installer with Windows ME, but we don't have enough information to fix it. Luckily, you can install the YIP copier manually and apparently it works. Unfortunately, the only info we have on the subject is extremely vague (we do know, however, that "gobbledygook" is involved). Anyway, here:
Now you should be able to stick files in the send folder and double-click on yipcopy.bat to upload them to yip.org. If you made a folder called stone inside the public_html folder and put the file moss.html inside it, you could then access it through http://www.yip.org/~you/stone/moss.html .
Return to the uploading section, or return to the Windows section.
