Description
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 Googles 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 doesnt 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.

FAQ
-
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.
-
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).
-
These people will leave their track on the log file. So check the log file regularly to see if there is someone youd like to bring into your subscribers database. The log will give you
that persons username, email and date/time when he tried to register and failed. Then its 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. -
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 dont know how long will it take till Google disable the old reCAPTCHAs API, so an automatic (forced) transition to the new version will be provided in future releases of this plugin.
