Captcha Control for Community Server 2.1
If you are like me and use CS 2.1 and want people to comment on your blog posts you have realized that you get way too much spam. There is something you can do about it, and that is to install a Captcha control. When the page is created an image with a random number, in this case, is created for the user to enter before submitting their post.
I am using Dave Burke's captcha control and the download link is posted below. I am hosting the zip because I have not been able to find it posted anywhere else. Hope this helps someone out there in the intrawebz.

Edit: After having this installed for about 2 months now I am glad to inform you that this works like a charm.
