"If you
only want to change the title of the site this is even
simpler.
Open up your web-browser, browse to
'Environment', then 'Header', hit
'Settings' and change the title field from '%k' (the name of the
current *k*ernel) to something else."
This is odd, following my instructions it works for me. What version
of Pier are you using? The image I have here is Pier-Model-lr.87 and
Pier-Seaside-lr.82.
How do you find out? I searched for a method to return the version, but
I didn't see any. Seems it ought to be in the seaside tests.
