Contact Enhanced solves an old issue for me. Since I started with Joomla 3 years ago I have always used Community Builder so I could engage their registration form, add fields, mark them mandatory and the most important part, add CB's captcha.
I know there are other methods for captcha that have been around for a while but I didn't care for them, hard to read, tricky installs.
Now with Contact Enhanced I was able to add a few fields to the my contact form and the big bonus is you have a choice of three different captcha's to use.
Contact Enhanced is a component and plugin, the plugin must be installed and published if you want a captcha to show. The plugin contains the captcha settings and the simple 'Math Question' is the easiest to read.
If you want to use Re-Captcha and help with the digitalization of old books you need the two 'Keys' which you get from the Re-Captcha website.
If you want to use either of the other two captcha choices you don't need anything special just make the changes in the plugin.
The support from Douglas is excellent to say the least! He really cares about people. There is a small cost to help with his time and bandwidth costs. It's still open source!
Thank you Douglas!
