Keypic checks your forms against the Keypic Web Service to see if they look like spam or not and lets you review the spam it catches under your blog's "Comments" admin screen. Keypic protect also your login form from brute force dictionary attachs, your registration form from unwanted spammers and generally all the forms you can imagine :) If you want a complete free antispam solution, you don't want to install CAPTCHAs plugins and so on, this is the right choice. Is also possible look at live installation at http://wordpress.keypic.com/

Major new features in Keypic 0.9 include:

• Contact Form 7 extension is included in keypic.
• It is no more needed to be registered, Keypic function also without registration, but with some limitations.
• Check of your FormID in Keypic Configuration
• Only if you are registered is available the comment status history, so you can easily see which comments were caught or cleared by Keypic, and which were spammed or unspammed by a moderator
• In the same way is possible users status history, so you can easily see which users were caught or cleared by Keypic.
• If your web host is unable to reach Keypic's servers, the plugin will automatically retry until the connection is back.

PS: You'll need an Keypic FormID to get improved functionality. Keys are free for every kind of use (It's free and will always be.)
