Re: International RSS-Feed (ISO-8859-1) needed
One idea more:
Could one of the PHP experts take a look at the implementation of XMLRPC of XOOPS. To download the package go to http://www.xoops.org].
I have used XOOPS more than 1 year and it works fine together with w.bloggar and similar apps. XOOPS has not a blog system, but you can manipulate articles over XMLRPC.
