mod_invites_page: Remove preauth URI button This button is incompatible with the majority of XMPP clients around, yet based on feedback from users, many are drawn to click it when they have any XMPP client installed already. In the case where the user already has software installed, we would prefer them to select it from the software list so they can follow the setup process suited to their specific client (we already track which software supports preauth URIs). If their client is not listed, they can still use the manual registration link instead.

summary: provides captcha protection for registration form
...

Introduction
============

Prosody-captcha is a little modification of prosody's
"mod\_register.lua" module that provides captcha protection for
registration form.

Installation
============

First of all you should build and install lua bindings for libgd —
[lua-gd](https://github.com/ittner/lua-gd/).

Then clone repsository lua-captcha:

    $ git clone https://github.com/mrDoctorWho/lua-captcha

install it:

    $ make install

Configuration
=============

After that you would configure prosody. This module requires from you 4
fields, you should add this into your VirtualHost entry.

    captcha_config = {
            dir = "/tmp"; -- Directory used to storage captcha images. Please make sure prosody user allowed to write there.
            timeout = 60; -- Timeout when captcha will expire
            web_path = "challenge"; -- Web path used to separate main prosody site from itself modules.
            font = "/usr/lib/prosody/FiraSans-Regular.ttf" -- Font used for captcha text
    }

You can run script "install.lua" to install this or instead of that
while prosody developers didn't accepted "dataforms" changes you should
replace standard prosody "dataforms.lua" located in ubuntu in
/usr/lib/prosody/util by another one from this repository. You should do
the same thing with "mod\_register.lua" located in ubuntu in
/usr/lib/prosody/modules.

After this all you can try to register on your server and see the
captcha.

TODO
====

-   Maybe use recaptcha instead of libgd.
