Does the same functionality as BuddyPress, emailing users who get mentioned in a bbPress topic or reply. The aim of this plugin is when to enable that feature when no BuddyPress is there. 
To do: – warn user about bbPress/BuddyPress presence

bbPress Mentions Email Notifications

Adds the @mentions to bbpress - really useful

Great plugin

Email bbPress topic/reply mentioned users, set custom email and some basic settings

A <a href="https://codex.wordpress.org/Create_A_Network" rel="nofollow ugc">Multisite</a> Network plugin.
Ever signup a user account, delete it, and try to signup up the same username again?
Ever try to support a new user who created a username, but entered the wrong email address and so can’t activate, and can’t signup with the same username?
Ever wanted to signup a bunch of users with phony emails so users without email could start blogging right away?
I have, so I made a plugin to help me.
WP Network Multisite “mu-plugin” for user activation key removal or approval.
See Network–>Users–>”User Activation Keys” to delete activation keys – to allow immediate (re)signup of users who otherwise get the “try again in two days” message.
Also, users waiting to be activated (or can’t because the email with the generated activation link is “gone”) can be approved manually.

User Activation Keys

This plugin saved me time to delete activation key directly in the database. It's much more easier to manage users in Multisite using this plugin. Thanks for the dev!



Must Have Plugin for Multisite

Works fine :)
