I have two questions about RSS which I haven't find answered in the forum.

First, "/rss.php?atom" works, but if I use "/rss.php" I don't get any message. Could it be something misconfigured in my forum or it's a bug?

Second, I'm using the application Feedreader to read the RSS feed. The channel configuration in this application includes fields for user name and password, but even if I fill this information with my IP user and password I get only the topics posted in public forums, I cannot read the topics in private forums or in forums for registered users. Is this a problem of Feedreader or a limitation/bug in IP?

Ok, I found the answer for the first question. I had added a name to the admin email address in the server configuration, in the way "Site name <admin@mysite.com>", so the user receiving the mail sees "Site name" instead the address. This was causing an error in this line of the RSS source:

<managingEditor>Site name <admin@mysite.com></managingEditor>

Because of the "<>" characters which are forbidden in XML as they are part of the XML itself. I'll try to fix it, may be leaving the address only in that field and then modifying the file/s which sends the email messages to add the site name before the address and put the address between "<>".

Anyway I still don't know about the second question.
