Fixed wrong user variable in lookup.html template for edit link (was user should be found_user).
There is no DeveloperForm in site/user/profile.py changed that to LookupForm.
from django.conf.urls.defaults import *
urlpatterns = patterns('examples.hello.views',
(r'^html/$', 'hello_html'),
(r'^text/$', 'hello_text'),
(r'^write/$', 'hello_write'),
(r'^metadata/$', 'metadata'),
(r'^getdata/$', 'get_data'),
(r'^postdata/$', 'post_data'),
