UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Adding the poster's name to the Notify Mod email and Email Users in Admin Control Panel

You can find some old mods for 6.5.5 over on ubbdev.com

As for emailing users. You use the member management tool in the control panel. Just search for the group of users you want to email, when you see the results of the search down at the bottom there will be a dropdown that has a few options, one of them being Email Members.
