Hi,
I'd like to ask 3 things:
1. What kind of captcha you have integrated and where can I see it?
2. Is there any way to integrate any antispam other than captcha-recaptcha? For example, if I install a different service and set it as the Joomla default, could I use it in ccomment as well?
3. Can a guest or registered user delete or edit his comment?

Thanks in advance.
