The homepage link http://www.rarewares.org/files/others is redirected (HTTP/1.1 301 Moved Permanently) to http://www.rarewares.org/files/others/ Both are valid URIs (rfc2396), so I suggest adding the trailing slash in order to avoid unnecessary redirection.
Might want to fix the email address in metadata.xml too :)
