## Опис

NURCaptcha stands for _New User Register Captcha_. It has been designed for anyone
who wishes to allow free registration of new users for a WP site, but want to keep
bots outside. It uses Google’s reCAPTCHA tools to give your site an extra protection
against those spammer bots, adding security to the WP Register Form. With Skt NURCaptcha
you may use a reCAPTCHA on your login form, also.

Skt NURCaptcha is easy to install and doesn’t slow down your site. It is called 
into action just at the moment the „Register for This Site“ form is requested. It
prompts users with a checkbox they click on to prove they are not robots, and creates
a challenge whenever needed, and checks the response given. If it is not valid, 
new user registration fails. If the response is valid, NURCaptcha leaves the scene
and your site runs as if it was not there.

Skt NURCaptcha adds (from Version 3 on) extra security by querying trustable antispam
databases for known ip, username and email of spammers, so you get rid of them even
if they break the reCaptcha challenge by solving it as real persons. From version
3.4 on you can enable login form protection, also, as an extra fence against brute
force attacks.

NURCaptcha also shows you each blocked attemptive. Log data may be toggled for you
to see info on the attemptives blocked by the plugin. It shows date/time of trials,
as well as usernames and e-mail addresses of those who failed registration (or login,
if enabled) and were kept outside. Please note that attemptives in which the spambot
suspends its attack when confronted by the reCAPTCHA challenge can not be logged.
So logfile figures will never reflect the whole achievements of the plugin in securing
your site.

Works smoothly with **WP Multisites** (Network) and **BuddyPress**.

## ЧПП

### The number of blocked attemptives is growing too slowly on the log. Does that mean that the plugin is not working?

If you was facing a greater number of spambot registrations than the figures you
see now in the log counter, that means the plugin is doing its job perfectly. Almost
all the spambots give up their attack when confronted by the reCaptcha challenge,
so they come and go silently. These bots may not trigger the counter, but they will
not get inside your site walls, either.

### Does NURCaptcha blocks spambots only?

That is the main target of any captcha plugin: to catch bots and allow human beings
to pass by. In order for it to somehow prevent you against badly mooded human intruders,
their data (email & IP) are checked against trustable anti-spam databases (from 
plugin version 3.0.0 on).

### How can I help people who for any reason were not able to fill the captcha challenge?

These people will leave their track on the log file. So check the log file regularly
to see if there is someone you’d like to bring into your subscribers database. The
log will give you
 that person’s username, email and date/time when he tried to 
register and failed. Then it’s up to you to add that user manually or send him an
email with directions for an effective registration. The most common problem that
keeps good people outside is not due to the reCaptcha, but illegal (non ASCII) characters
in usernames. That is why we added a help box to the register form.

### Why there are two versions for the reCAPTCHA?

On december, 2014, Google released a new version of reCAPTCHA. This new version 
is more friendly to the user and far more advanced in technology, if compared to
the former version. If you are upgrading from an older version of Skt NURCaptcha,
we strongly reccomend you to enable the new version, in the settings page of this
plugin. If you have this version of the plugin in a fresh installation, the new 
version of thr reCAPTCHA is enabled by default. The only reason to keep both versions
of reCAPTCHA is to allow old users to prepare for the change. We don’t know how 
long will it take till Google disable the old reCAPTCHA’s API, so an automatic (
forced) transition to the new version will be provided in future releases of this
plugin.

I immediately apologize, but for whom you write such instructions? For developers,
programmers? So they themselves know how to write code and they don’t need plugins!
Is it not possible to write: step 1 enter the following script into the file function.
php, step 2 enter the script in the file … step 3, enter the script in a file …???
That’s the second step I don’t understand?

I tested several plugin in the same style and for me this is the best and more consistent
BuddyPress. I made a French translation, if you need contact me
