|
|
%%% IDEAS:
|
|
%%%
|
|
%%% * Implement those options, already present in mod_register:
|
|
%%% + access
|
|
%%% + captcha_protected
|
|
%%% + password_strength
|
|
%%% + welcome_message
|
|
%%% + registration_timeout
|
|
%%%
|
|
%%% * Improve this module to allow each virtual host to have different
|
|
%%% options. See http://support.process-one.net/browse/EJAB-561
|
|
%%%
|
|
%%% * Check that all the text is translatable.
|
|
%%%
|
|
%%% * Add option to use a custom CSS file, or custom CSS lines.
|
|
%%%
|
|
%%% * Don't hardcode the "register" path in URL.
|
|
%%%
|
|
%%% * Allow private email during register, and store in custom table.
|
|
%%% * Optionally require private email to register.
|
|
%%% * Optionally require email confirmation to register.
|
|
%%% * Allow to set a private email address anytime.
|
|
%%% * Allow to recover password using private email to confirm (mod_passrecover)
|
|
%%% * Optionally require invitation
|
|
%%% * Optionally register request is forwarded to admin, no account created.
