Contact
The original author of this plugin was Denny Lin. I forked it some years ago to 1) use reCAPTCHA v2.0, 2) add the larry skin and 3) because the project issues were taking too long to be answered. Also, the original project was not updated since 2015 and many things have changed in the meantime in Roundcube's API.
I will maintain this project because i need it working with the latest version of Roundcube.
Comments and suggestions are welcome (preferentially via issues).
