Ive updated Turtushout for usage on production sites and added:

• spambots protection, ip logging and antiflood (see advanced parameters in module properties, and dont forget to change secret salt)
• additional display settings in module< /li>

Also some bugs where fixed, thanks for your comments. More about safe forms without captcha (hate them) you could read for example here

sql query to execute after upgrade:
ALTER TABLE `jos_turtushout` ADD `ip` VARCHAR( 255 ) NULL ;
