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.

Type complex math expressions easily into your wordpress page using MathQuill (http://mathquill.com/). This plugin adds a new block editor called ‘Direct math input’ in the ‘widgets’ category.
Math expressions are saved in LaTeX format and rendered by MathQuill during pageview.
<h4>Usage</h4>
After installing, a new block editor called ‘Direct math input’ will be available. Each block contains a MathQuill instance 
where you can edit math right on your page.
When the math editor is focused, you can enter math symbols using your keyboard or via copy/paste. 
See the http://mathquill.com/ homepage for a visual demonstration of how to input math.
Some common keyboard shortcuts are as follows:
<ul>
<li>/ (forward slash) Enter a new fraction, with focusable input areas for numerator and denominator</li>
<li>^ (caret) Enter a new superscript, e.g. to add an exponent</li>
<li>_ (underscore) Enter a new subscript </li>
<li>( (open parentheses) Open parentheses (which will scale based on the height of the content inside) Other parenthesis types behave similarly, e.g. [ and {</li>
<li>\ (backslash) Start typing one of the control sequences below. When finished, press enter or space to see the resulting symbol</li>
</ul>
Control sequences – to create each symbol, type the full sequence (including the backslash) into the math editor, followed by 
space or enter. (not an exhaustive list)

<li>\plusminus</li>
<li>\times</li>
<li>\alpha</li>
