Mollom plugins
Mollom for SilverStripe
SilverStripe users rejoice because Dieter Orens created a Mollom module for SilverStripe, an Open Source CMS developed in PHP. The module is available from http://mollom.silverstripe.be. The module only implements Mollom's CAPTCHA service at this point. Thanks Dieter!

.NET library for Mollom
Friend of the family, Jelle Druyts wrote a Microsoft .NET library for Mollom. Jelle and I went to the same high school. I've kept up with Jelle over the years and consider him to be on the forefront of everything Microsoft. I've never had the opportunity to work closely with Jelle until more recently, when Jelle offered to contribute a .NET library for Mollom. Jelle's thinking and diligence wowed me -- and best of all, he is still the warm and fun human being that he was in high school. Check out Jelle's announcement for more details. Thanks, Jelle!
