1. User Preferences

You can predefine, disable or remove several options on the user preferences page using the following parameters in your wiki config:

Variable	Default	Description
user_checkbox_defaults	dict	Sets the default settings of the user preferences checkboxes. Example: `user_checkbox_defaults = {'edit_on_doubleclick': 0}`
user_checkbox_disable	`[]`	a list of checkbox names to be disabled in the user preferences. A disabled checkbox is displayed greyedout and uses the default value set in `user_checkbox_defaults`.
user_checkbox_fields	`[...]`	list of checkbox items.
user_checkbox_remove	`[]`	a list of checkbox names to be removed from the user preferences. A removed checkbox uses the default value set in `user_checkbox_defaults`.
user_form_defaults	`[]`	a list of form defaults for user preferences.
user_form_disable	`[]`	a list of form field names to be disabled in the user preferences. A disabled field is displayed greyed out and uses the default value set in `user_form_defaults`.
user_form_fields	`[...]`	list of user preferences form items.
user_form_remove	`[]`	a list of form field names to be removed from user preferences. A removed form field uses the default value set in `user_form_defaults`.

The possible keys / clear text explanations are found in MoinMoin/config/multiconfig.py:

Variable	Description
mailto_author	Publish my email (not my wiki homepage) in author info
edit_on_doubleclick	Open editor on double click
remember_last_visit	After login, jump to last visited page
show_comments	Show comment sections
show_nonexist_qm	Show question mark for non-existing pagelinks
show_page_trail	Show page trail
show_toolbar	Show icon toolbar
show_topbottom	Show top/bottom links in headings
show_fancy_diff	Show fancy diffs
wikiname_add_spaces	Add spaces to displayed wiki names
remember_me	Remember login information
want_trivial	Subscribe to trivial changes
disabled	Disable this account forever

So you could do, for example:

user_checkbox_remove = ['edit_on_doubleclick', 'show_nonexist_qm', 'show_toolbar', 'show_topbottom', 'show_fancy_diff', 'wikiname_add_spaces', 'remember_me', 'disabled',]

user_form_remove = ['password', 'password2', 'css_url', 'logout', 'create', 'account_sendmail', 'aliasname',]
