CMS & WordPress
I am looking for plugin where visitors can post, and comment without logging in or registering.
I want it to automatically create a username for them, and it save them as that 'login' via cookies (I think)
if they visit the next day they can still post via that username.
This plugin just for that - wordpress.org/extend/plugins/wordpress-guest-post
Yeah ..you can post your guest post ..By login into that site . But remember that your post will be reviews by site admin.
Try this plugin .
this plugin support anonymous guest posting in both free and paid mode - phppoet.com/wp-guest-posting-plugin-for-wordpress/
It supports both sided payment mode . admin can pay to bloggers and bloggers can pay to admins .
