Contact Form restrictions to contact POSTER
#1 how can i make the contact poster form restricted only to register users
#2 can I set to be restricted to a specific user?
for example;
The ad poster is AUTHOR. they can only post ads, but they can NOT contact other posters.
and only EDITOR can post ads and contact posters
how can I do that?
Can I set up different pages to register?
Thanks in advance.
