Konqueror does not work with roundup.
You can display stuff, but submitting information does
not work.
This is most likely a konqueror bug. However as
Konqueror is established and roundup is not, people
will most likely perceive this as a roundup bug. (This
has happened to me a couple of times.)

Thus we should document this missbehaviour in detail, 
check for the bug id within the KDE bugtracking system,
open a new bug if necessary and follow the issue.

Konqueror is my primary platform. What version do you see the problems 
with?

A couple of my users had problems with this.
Not all of their konqueror versions are known to me.

I could also see problems with several konquerors (e.g. KDE
3.1 RC3
and Konquorer 2.2.2) I can log in, but submitting of details
does not work.
This might be related to the webserver I using (Caudium).

Just found out that my testsystem with the roundup
standalone webserver works, if I accept the right cookies.
After the first cookie I somehow got
logged out again because there are two DNS names for the
server machine. This covered up that it works.

Thus I have to further inquire the roundup <-> caudium
connection.

It is a Caudium bug.
Reported and patch created.
