Re : Contact Us
Hi drpeck,
on ReleaseProcess181 you can read
- Contact Anonymous fixed by marclaporte and Damian
remember to enabled the Contact Us and user Messaging features, set a contact name on Admin->General and let anonymous use the messaging system permission
So I guess you want to be using a CVS tarball.
For second question, I think the Application menu in Admin Menus is not in use by default, but a hardcoded one. you must assign it to a module and remove the other one.
Feel free to come on IRC #tikiwiki if you have more questions 😉
