This functionality is available in Spacious ACP. This plugin will be removed in the near future as IPS cleans up old MP entries.
This plugin will allow admins to start a conversation with members directly on their profiles on Admin CP.
Version 1.0.1 is for 4.2.x and lower. Use the version selector below to download this one.
Version 2 is for 4.3 and above.
If you have Spacious ACP you do not need this, it's built in to Spacious.
