Works like a charm on Buddypress, shows up on custom register-forms as well as all the regular forms.

Quick, Easy, Straight In
By , for WP 3.5.1

The author of this plug-in has a grand total of three plug-ins published and I'm using all of them. Configuration has been easy in all cases, particularly with SI CAPTCHA Anti-Spam and, while the CAPTCHA itself may not be the most sophisticated in the world, if it works, it works (and it does, by the way) - if not, I haven't spent a whole lot of time setting it up and won't bewail the lost effort.

I Love this plugin

works smooth on all wordpress updates

Works perfect on all wordpress updates we had until now (current version 3.5.1).
It's one of the not so many plugins that do not stop working after a wordpress upgrade.
We have installed it on the login page of admin, registration and lost password pages of all wordpress installations and this helps against spammers and brute force attacks enormously.
Great job, Mike!
