Hi

I have 2 questions:

1. Does this plugin work with bender Theme?
2. Does this plugin use recaptcha or another antyspam solution?

@selerfont
1) yes
2) it should be enabled for logged-in users only, then no recaptcha is required

Ad. 2.

But what about NON logged user? Is there recaptcha or another antyspam solution?

@selerfont
I do not think that is good idea nowadays.

So non logged users can't send messages to sellers?
Or the can, but this plugin should be enabled for logged-in users only, because there is no captcha?

@selerfont
If I am not wrong, sending messages by logged out users has been disabled several versions ago.
