OK, so we have
Help::listLink() for online help
Prefs::listLink() for options
????::listLink() for problems, to which class should we add the listLink for
problem? Create a new Problem class? (Is naming a class "Problem" asking for
problems? ;-) )

If nobody has any further objections (Jan?) I'll put some effort in it this
weekend and create a monster patch with all modifications for the 
framework and
all modules. (If we have a verdict on where to place the listLink method for
Problem)

Cheers,
Roel.
