A simple equation solver used as a CAPTCHA


This is a small plugin to present an anonymous user with simple math addition problems in order to submit a new ticket or to make edits in the wiki. Currently there is no customization: it presents two integers in the range of 1 - 10 and asks the user to add them together.

For the future, would be nice if there were multiple types of math problems presented in a way that wouldn't be easy for a bot to recognize.
