after reading this thread I'm still confused about the recaptcha implementation in Acymailing 6.
In the configuration security section we have filled out the google keys for version 2 of Recaptcha. On the Acymailing 6 subscription form (Joomla module) there isn't any captcha on the form.
Is this because
1) we haven't configured something correctly
2) Acymailing 6 does NOT implement the google captcha on the subscription form
3) Acymailing 6 does implement the google captcha on the subscription form BUT it needs to be version 6 i.e. the invisble recaptcha.
Looking forward to the clarification.
