Important: Since version 2.0, this plugin now requires at least PHP 5.3. Please ensure you are running the latest available version of PHP on your server.

This plugin adds <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google’s reCAPTCHA</a> to the BuddyPress registration page and WordPress login page to prevent bots from registering and keep your site free from spam registrations.
reCAPTCHA is “tough on bots, easy on humans”: while it is increbianle effective on preventing bots from registering, most of the time all the user needs to do to verify themselves is simply check a box.
After installing this plugin, you will need to <a href="https://www.google.com/recaptcha/admin" rel="nofollow ugc">register your site with Google</a> (requires a Google account) and enter the site key and secret key on the Settings > BuddyPress > Options admin menu. If you would prefer not to use Google’s service, there is an alternative security check method also available; see below;
Prior to version 2.0, a less effective security check method was used where the user needed to answer simple math sum before registering. This method is still available, and can be turned on on the Settings > BuddyPress > Options menu.

NOTE: For must users, we recommend using <a href="http://jetpack.me/" rel="nofollow ugc">Jetpack</a> and 
its <a href="http://jetpack.me/support/beautiful-math-with-latex/" rel="nofollow ugc">Beautiful Math feature</a>. 
WP LaTeX offers additional control since it allows you to host your own LaTeX 
image server.
Writing equations and formulae is a snap with LaTeX, but really hard on a website. 
No longer. This plugin combines the power of LaTeX and the simplicity of WordPress 
to give you the ultimate in math blogging platforms.
Wow that sounds nerdy.
