Why did you uninstall SI captcha?
SI CAPTCHA Anti-Spam works with Wordpress 2.6+, WPMU, and BuddyPress

http://wordpress.org/extend/plugins/si-captcha-for-wordpress/

WP-reCAPTCHA is not up to date for BuddyPress 1.1, that is why it does not work.

@Mike Challis: I need a captcha plugin that can be enabled sitewide. But it seems that SI captcha can’t enabled sitewide; every user needs to enable it manually.

This is how to install SI Captcha globally on WPMU.

Step 1: upload the /si-captcha-for-wordpress/ folder and all it’s contents to /mu-plugins/

Step 2: MOVE the si-captcha.php from the /si-captcha-for-wordpress/ folder to the /mu-plugins/ folder.

Please report back here is this worked for you.

I am not able to get it working. I do get following errors:

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home1/kailas/public_html/blogs/wp-content/mu-plugins/si-captcha.php on line 90

Warning: Invalid argument supplied for foreach() in /home1/kailas/public_html/blogs/wp-content/mu-plugins/si-captcha.php on line 93

OK, I see the error on my test site now. I will try to fix it.

This should be fixed now. You have to install this new version.

== Changelog ==

= 2.0.6 =
- (13 Oct 2009) – Fixed array_merge error on WPMU, Buddypress.
- Added Czech (cs_CZ) – Translated by [Radovan](http://algymsa.cz)

@Mike, thanks for taking care of this. I will give it a try now.

You can also try this method if you aren’t running WPMU, and nothing else seems to work for you. Just a note, it does require you to change a BP core file. http://adlatitude.posterous.com/how-to-include-recaptcha-into-buddypress
